The aim of this blog guide is to inform you about the role of Kadolta Packaging tamper-evident label seals in terms of packaging security and why it matters. Not forgetting, when it comes to Kadolta Packaging Limited, there are an array of products and equipment that we do offer. As well as other prior and after-sale services and solutions to all our customers.

Most restaurant operators and consumers alike are familiar with tamper-evident labels and seals. Everyday items such as over-the-counter drugs, food items, packaging materials, cleaning solutions, and laundry products now often employ this method of security. Many manufacturers are now required to use these labels on their products.

With the surge in the popularity of third-party delivery, tamper-evident labels have taken on a more prominent role in the restaurant industry. Safety and peace of mind. Especially when it comes to food delivered to a home or office, consumers want to make sure their food tastes good, is delivered within a reasonable amount of time, and is safe to eat.

Above all, they want to know that the food has not been tampered with in any way from the time it left the food service kitchen to the time it arrives at their door. Be that as it may, KadoltaPack is one great place to get some of the best tamper-evident label seals in the marketplace. That said, there are some key things to know about these labels…

Marketplace Basics About Tamper-Evident Label Seals From A Manufacturer

As defined by the Food and Drug Administration (FDA), tamper-evident label seals “are one having one or more indicators or barriers to entry which, if breached or missing, can reasonably be expected to provide visible evidence to consumers that tampering has occurred.” The FDA goes on to say that the indicator or barrier must be “distinctive by design.”

This means, that the tamper-evident feature is designed from material not readily available to the public. “Therefore, it can’t be easily duplicated.” So, what is the “visible evidence” that a tamper-evident seal provides? While this may vary by type and manufacturer, TamperSeal Labels — manufactured by DayMark Safety Systems — feature security slits.

Uniquely, there are cuts on the surface of the label that tear if someone attempts to open the container, making it visibly obvious the package has been opened. But, are tamper-resistant and tamper-evident labels and seals the same? Well, no, they are not — and this causes a lot of confusion. A tamper-resistant label is designed to deter tampering with a product.

However, it does not necessarily provide visual evidence that a product has been tampered with. A tamper-evident label seal, on the other hand, as described by the FDA, does provide visible evidence that a product has been tampered with if the seal is broken in any way.

Why The KadoltaPack Tamper-Evident Label Seals Marketplace 

As an example, the Tamper-Evident Label Seals from Kadolta Packing Limited ( open up a wide range of possibilities in the marketplace to both sellers and buyers. Particularly, for providing medicines and other packaging materials with proof that the package has not been opened by an unauthorized person (tamper-evident) – in an economical way.

As a matter of fact, that’s why even the regulation 2016/161/EU obligates pharmaceutical manufacturers to place such anti-tampering security features on their prescription-only medicinal products. Pharmacies may only dispense medicines to patients if the packages have an appropriate tamper-proof seal as protection and proof of authenticity.

Overall, this ensures that no changes (which could harm the patient) have been made to the finished medicinal product. During the testing of manufactured medicinal products, the packaging may nevertheless be opened and tested by the pharmacist; dispensing to the patient is then still possible with a relevant note from the pharmacy. Below are the KadoltaPack benefits:

1. Flexible and pliable – for reliable application

In terms of economic viability and technical practicality, conventional rectangular or round labels, preferably with additional security perforations, are the best solution. The label material, which is usually transparent PE or PP film, is especially flexible and pliable – ideal for labeling around corners. The adhesives are highly resistant to water, hot air, and a variety of solvents.

Only if these conditions are met is the label impossible to peel off. More so, even from highly varnished cartons, without either being destroyed or visibly damaging the surface. For, especially, difficult surfaces, special adhesives are available, and the labels can additionally be provided with security perforations. But, one and the same sealing label variant can be used.

Particularly, with an abundance of packaging materials and numerous different surfaces. Of course, the best thing is to opt for transparent tamper-evident label seals. For one thing, their uniquely designed glossy material does not cover the information on the package or interfere with the brand image. It’s also very easy to seal off once it reaches the intended customer.

2. Any unauthorized package opening protection

The final adhesive strength of the likes of Kadolta Packing Limited tamper-evident label seals is very powerful. Meaning, that sealing labels equipped with this adhesion can neither be removed from dispersion-varnished folding boxes nor from many other polar and non-polar surfaces. Such as paper, cardboard, and even plastics and steel.

Not without being destroyed nor leaving visible residues on the surface. This ensures effective protection against the unauthorized opening of medicines. Labels can also be given special characteristics, such as luminescence, to facilitate the inspection process.

3. Security features for maximum counterfeit protection 

Punched security perforations in the label can further enhance counterfeit protection for drugs. The security labels connect the tuck-in flaps firmly to the package body, providing proof of product authenticity and clear evidence that the seal has been broken. Any attempt to open it will destroy the label. Besides sealing labels, a company like KadoltaPack is a great source.

Since they also offer labeling machinery that can be integrated into your packaging facilities for perfectly coordinated production. Attaching tamper-evident labels requires a high degree of precision. The labels, which are usually very small, must be stuck to the side of the tuck-in flap in such a way that they protrude by about half their length up the packing material.

As well as half their length down beyond the body of the folding carton. A folding rail then “irons” the two unattached parts of the label through 90 degrees, and foam rollers press the labels against the pack so that the tuck-in flap is permanently affixed to the carton. The machine is equipped with sensors for checking the placement of the labels and rejecting any defective ones.

4. Tamper resistance and proof of authenticity

There are many names for labels of this kind: security labels, anti-tamper labels, tamper-evident labels, and anti-counterfeiting labels. What they all have in common is a focus on tamper protection and product authentication. In reality, the best thing about Kadolat is that their sealing labels clearly show that the products have not been opened or tampered with.

They can be applied to all kinds of surfaces: film, cardboard, paper, plastic, or metal. Kadolta offers a wide range of high-security solutions. Their specialists will produce sealing labels for you made of special composites (tamper-evident, void) and with security perforations. Also for extreme conditions, with extremely strong adhesives, on rolls, printed or unprinted, etc.

KadolataPack also has a very versatile packaging method. Whereby, sealing labels can be applied to packaging made of film, paper, plastic, metal, or glass, ensuring secure closure even when used on corners on uneven surfaces. They can even hold cardboard boxes together. Find out for yourself and benefit from the expertise of KadoltaPack application engineers…

In addition to special tamper-evident label seals, the great KadoltaPack team offers sealing solutions for a wide range of requirements as per their customer needs and specifications. For example, in the packaging of a variety of marketplace goods and products such as foodstuffs, right? But, the main benefit comes in handy in terms of the resealing process.

Unlike others, the KadoltaPack re-sealing labels allow easy resealing of packages that have been opened. No damage is done to the packaging. The product is kept fresh and is ideally protected – your customers will appreciate this because they will not need any other kind of seal.

Sealing labels are manufactured from the film, sometimes with partial adhesion. Special stamping and gripping tabs ensure easy use. Whether you need printed or unprinted labels, Kadolat can produce them on rolls to your specifications. They can be applied to film, cardboard, paper, or plastic.

How To Choose The Right Tamper-Evident Label Seals For Packaging

If you do not find the material therein that you had expected to be on the list, please reach out to us! It is very likely that we will be able to help you with your packaging needs or point you in the right direction to a solution.

That said, when sourcing a tamper-evident label seal for packing, it is suggested that you research the different types available and work with a local packaging expert to identify the best possible material for your specific needs. Depending on the products that you will be packaging, there may be many different tamper-evident materials that would work for your needs.

What to look for in tamper-evident label seals: 
  • Economical, without changing the folding box design
  • Cannot be pulled off non-destructively and residue-free
  • Suitable for different surfaces like cartoons, plastic, wood, etc.
  • Pliable, ideal for small radii and labeling around corners
  • Glossily transparent where nothing else is covering the package
  • The adhesive is extremely resistant to water, solvents, and hot air
  • System solution for labels and labeling system from one source
  • Standard formats available immediately from the warehouse
  • Customized designs to match your specifications

With that in mind, there are a few types of tamper-evident label seals that you can consider in your next packaging process. Below are some of those memorable mentions that your business or company can opt for getting started.

1.  Tamper Evident Tape & Overwraps

Basically, when sourcing tamper-evident packaging materials, it’s good that you research the different types available and work with a local packaging expert to identify the best possible material for your specific needs. Depending on the products that you will be packaging, there may be many different tamper-evident materials that would work for your needs.

Tamper-evident tape is the first option — it utilizes a security seal for shipping pallets, boxes, crates, and various other types of containers. Once you have applied it to a surface, it cannot be removed without triggering tamper evidence. Perse, it’ll leave a message behind such as “open” or “void” on the remaining tape after attempted removal.

Next is the overwraps. On one hand, overwraps are pieces of plastic film that have been wrapped around a product and sealed with heat or adhesives. For example, the cellophane plastic covering on a pack of cigarettes is an application of over-wrapping used on various products. Overwrapping gives the product an air of cleanliness, protection, and quality.

Overwraps, on the other hand, also provide a branding opportunity since they can be printed with multiple colors, text, and visual components. But, overwrapping differs from shrink film in that the over-wrap is wrapped around the product. After the overwrap is placed around your product, the flaps of the plastic are tucked and sealed by a machine.

2.  Lidding Films & Shrink Films

In reality, lidding films have been a staple of tamper-evident packaging for quite some time now. If you have ever eaten yogurt or bought over-the-counter pain medication, chances are, you removed a lidding film before consumption of the item inside the container. Some are plastic, metal, or bio-based materials used on a ton of different products.

More so, where freshness is essential. For example, when you buy a tub of yogurt after you remove the plastic lid, there is usually a lidding film made from aluminum underneath. It is sealed around the edges and is removed by pulling a tab. The tab protrudes out from the lid. Peeling the tab back generally results in the cap being removed from the container.

That being said, sometimes the tab will come off and result in you having to find more creative ways to remove the lidding. This can frustrate your customer and may cause them to feel a sense of wrap-rage. In essence, some forms of lidding films use MAP (modified atmosphere packaging) to keep your products fresh for as long as possible.

Not to mention, you may also see MAP applications in lidding films primarily for meat, poultry, fish, and vegetables. By the same token, shrink film is plastic that shrinks to form around the product packaged via exposure to a heating element such as a shrink tunnel.

3. Shrink Bands 

To enumerate, shrink bands (AKA seal bands) are one of many types of protective packaging and are tamper-evident materials created from plastic. They are small sleeves of shrink film that are shrunk around product containers. Shrink bands are sometimes perforated to be user-friendly. Shrink bands match the specific size of the top of a container.

Typically, you’ll find these around the cap for products such as pill bottles, pickle jars, eye droppers, essential oil containers, cough medicine, and other similar products. Essentially, a shrink band is a ring made from soft plastic. The ring is put around the product’s cap. Next, heat is applied to the ring resulting in uniform shrinking of the ring around the lid.

Usually, this process is generally carried out with a heating element such as a heat tunnel or heat gun. If products using a shrink band are tampered with or damaged, the shrink band shows that the product has been compromised. Perforated shrink bands have a better end-user experience because of less potential for wrap-rage.

4. Induction Seals

Technically, induction seals are packaging supplies made from induction heating thermo-plastic materials. You will commonly find induction seals on the inside of pill bottles. Generally speaking, it will be a multiple-material lid (most often aluminum, wax, paper pulp, and plastic) with a piece of plastic protruding from the top for packaging purposes in this case.

Eventually, this is meant to be gripped and pulled to remove the seal from the bottle. These seals are most commonly found on drug, food, and liquid containers and for items that have a long shelf life. Induction seals act as a tamper-evident substrate which, if torn, alerts the consumer to the potential tampering or damage to the product before them consuming it.

What’s more, induction seals help to keep your product from leaking, preserve freshness, alert you to tampering, and produce an all-around better product. Suffice it to say, that they are most commonly found in millions of products if you look around keenly. And, of course, they can be used for various types of applications for perishable items as well.

5. Resealable Stand Up Pouches

By all means, these are some type of resealable stand-up pouches with tear-away lids option features. For your information, stand-up pouches first made a splash in the B2C market way back in the 80s/90s. In particular, with an obvious shelf appeal for the famous Capri-sun brand of drinks for kids. Since then, they have come a long way to where they are today.

Notwithstanding, they are also fast becoming the chosen flexible packaging material for countless products for thousands of brands. Today you can find everything from industrial hemp to granola, from candy to toys, and millions of other items in between packaged in resealable pouches. The meteoric rise in popularity of resealable stand-up pouches is clear.

It stems from being easily branded with vivid color and design aesthetics and helps, save money because of less shelf space. From an environmentally conscious perspective, stand-up pouches take up less space in landfills – and are one of the most environmentally friendly materials currently available. Furthermore, they can be resealed after initially opening.

Remarkably, these pouches have become widespread across various product lines, and this can be seen by browsing your local supermarket. There are also child-proof resealable pouches that are used in pharmaceutical applications as well as medical marijuana dispensaries. In this respect, resealable pouches have a vast and varied selection of potential applications.

What To Expect From The Futuristic KadoltaPack Tamper-Evident Label Seals 

Generally, as you can see, from the list above, shrink bands are an excellent example of tamper-evident packaging supplies. If products using a shrink band are tampered with or damaged, the shrink band shows that the product has been compromised. Perforated shrink bands have a better end-user experience because of less potential for wrap-rage.

Given the transition of digital online web technology impacts, Kadolta Packaging Limited is also not left behind. Perse, their sealing labels can also be used as promotional labels, for example, to convey advertising messages. So, go and get the most out of their sealing labels by adding product information, best-before dates, batch numbers, instructions on use, etc.
