What Are the Differences Between PVC and PET Shrink Film? - HYF

Shrink films are widely used for packaging products, offering a tight, protective wrap that ensures items are secure and tamper-evident. Among the most popular shrink film materials are PVC (Polyvinyl Chloride) and PET (Polyethylene Terephthalate). These two materials are commonly used, but they have distinct differences that affect their suitability for various applications. In this article, we’ll explore the differences between PVC and PET shrink film, their advantages and disadvantages, and when to choose one over the other.

What is PVC Shrink Film?

PVC shrink film is made from Polyvinyl Chloride, a synthetic plastic polymer. It is one of the oldest and most commonly used shrink films in the packaging industry. PVC is known for its excellent clarity, ease of use, and ability to form tightly around products when heated. It is commonly used for packaging a wide range of items, from food products to toys and consumer goods.

What is PET Shrink Film?

PET shrink film is made from Polyethylene Terephthalate, a type of polyester. PET is a highly durable and versatile material, offering great resistance to impact, tearing, and heat. It is known for its strength, clarity, and resistance to environmental factors such as UV light and moisture. PET is often chosen for premium products or those requiring enhanced protection and visual appeal.

Key Differences Between PVC and PET Shrink Film

1. Material Composition

The fundamental difference between PVC and PET shrink films lies in their chemical composition. PVC is a vinyl-based polymer, while PET is a type of polyester. This difference affects their physical properties, performance, and environmental impact. PVC has been around longer and is often less expensive, while PET is more modern and is becoming increasingly popular due to its durability and strength.

2. Shrinkage Characteristics

PVC shrink film tends to shrink more evenly and consistently when heat is applied. This makes it an ideal choice for wrapping irregularly shaped objects. PET, on the other hand, offers a more controlled and uniform shrink, making it suitable for packaging products that require a tight fit and a polished, smooth finish. While both films shrink at high temperatures, PET tends to provide better stability in extreme conditions.

3. Clarity and Visual Appeal

One of the major differences between PVC and PET shrink films is their clarity. PVC offers excellent clarity, which makes it a top choice for products that need to showcase their appearance, such as toys or food items. PET, however, offers superior optical properties, providing a clearer, more premium look that makes it ideal for high-end products. PET films are often preferred when a high gloss finish is required to enhance the product's aesthetic appeal.

4. Durability and Strength

In terms of durability, PET has a significant advantage over PVC. PET shrink film is stronger, more resistant to punctures and tears, and can withstand higher temperatures without compromising its integrity. It is particularly ideal for products that need enhanced protection during shipping and storage. PVC, while still durable, is more prone to cracking and tearing under certain conditions and tends to degrade faster when exposed to UV light.

5. Environmental Impact

Environmental considerations play a growing role in packaging choices. PVC is known to be more harmful to the environment because it is difficult to recycle and may release toxic chemicals during its production or disposal. PET, on the other hand, is more eco-friendly and can be recycled more easily, making it a better choice for sustainable packaging solutions. PET is often used in the production of bottles and containers, and it is considered a more environmentally responsible option.

6. Cost

In general, PVC shrink film tends to be less expensive than PET shrink film. This is because PVC is produced in large quantities and has a long history of use in the packaging industry. PET, while slightly more costly, is often considered a worthwhile investment due to its superior durability, strength, and environmental benefits. The choice between PVC and PET often comes down to balancing cost with the desired quality and sustainability.

7. Application Suitability

Both PVC and PET shrink films are versatile, but their applications vary slightly. PVC is commonly used for wrapping food products, CDs, DVDs, and low-cost consumer goods. It’s perfect for products that need to stay intact and protected without requiring a premium look. PET is typically used for higher-end products that require extra protection, such as cosmetics, electronics, and specialty foods. Its strength, clear finish, and ability to maintain structural integrity in tough conditions make it a better choice for products that demand higher standards of protection.

Which Shrink Film Should You Choose?

The choice between PVC and PET shrink film largely depends on the specific requirements of your packaging project. If you're looking for an economical solution for basic packaging needs, PVC may be the better option. However, if you need a more durable, eco-friendly, and visually appealing packaging solution for high-end products, PET might be the way to go.

Conclusion

Both PVC and PET shrink films are excellent choices for packaging, but they each have their unique strengths and weaknesses. PVC offers a cost-effective solution with great clarity and ease of use, making it ideal for a wide range of products. PET, while slightly more expensive, provides superior strength, durability, and environmental benefits, making it the go-to choice for premium products. Understanding the differences between these two materials can help you make an informed decision based on your product's needs and your sustainability goals.

Need Help Choosing The Right Shrink Film?

The Environmental Impact Of Shrink Film

Shrink film is made of plastic. You may wonder why this would be a good choice when choosing earth-friendly materials. Based on science, shrink wrap is one of the most environmentally friendly options.

How is that possible, you may wonder? Simple. It all comes down to the heavy carbon footprint of some packaging materials.

Materials such as glass, metal, cardboard, and paperboard are recyclable. But, due to contamination in recycling, many of those items end up in the landfill.

The Shelf Appeal Of Shrink Film

One of the most sought-after benefits of shrink wrap is shelf appeal. Shrink wrap gives a beautiful glossy sheen to your products. The packaging entices customers to reach for your products.

The film's glossy surface reflects light and shimmers under retail store lighting fixtures. This gives it an upper-hand in the battle for consumers' attention.

For example, as an avid tea drinker, I go through a box or two of herbal tea per week. My two favorite brands are Bigelow and Celestial Seasonings. The latter is not only my favorite brand of tea but also one which uses this type of film in their packaging. The outer barrier of the film on these teas keeps the tea inside fresh longer, and it's easy to open making it a big win for me.

Celestial Seasonings packages their tea in wax paper bags. Then, they are sealed in a paperboard box. Finally, the paperboard boxes are shrink-wrapped in transparent plastic shrink film. The film gives their tea boxes a nice glossy sheen. This separates them from their competitors.

Do you want to use shrink film to help your product stand out? If you want to take shelf appeal to a whole other level, you may want to consider using printed shrink wrap.

Printed film has the same great benefits as transparent shrink wrap. But, it has the bonus of printing and branding capabilities. Printed film allows your product to stand out. It does this while reducing the added costs of printed labeling!

The only downside to adding shrink film to your products is that using additional materials comes with added cost. Adding more packaging may not be something you want to do as a cost-conscious business.

However:

Think of ways you can utilize shrink film to eliminate other types of packaging you are using. In many cases, shrink packaging can replace alternatives altogether!

The Pros And Cons Of Shrink Film

We have touched upon many shrink-wrap packaging elements. It can be a lot of information to keep track of. Do you want to simplify your buying decision and make the right choice for your packaging needs? Then you need to see the good and the bad. Here, we will review the pros and cons of shrink film.

Pros Of Packaging Your Products In Shrink Film:

Lower cost than most of the popular alternatives.
High shelf appeal.
Eye-catching glossy surface.
The lowest carbon footprint of most popular packaging materials.
Takes up less space in landfills than the other options.

Cons Of Packaging Your Products In Shrink Film:

Hard to recycle.
Not appropriate for ultra-heat sensitive products.
Not suitable for interactive products.
Not always good for luxury packaging applications.
If used as a secondary packaging material, it will increase the cost of your packaging.

Where Should You Buy Shrink Film?

When it comes to purchasing your film, you have several options. You could buy your film through online vendors with e-com stores such as Amazon. Many people like to buy from online stores to avoid travel and human interaction.

Buying online is also one of the fastest ways to fulfill your orders. But, many e-com stores do not have extensive information about the products. You may not find all the required information necessary to purchase the right film.

Buying directly from the manufacturer is another popular way to buy your film. Many buyers prefer to get their films directly from the manufacturer. They will always have a ton of information about each of the formulations of film they offer. And, they can help you choose the right film for your machinery, packaging line, and products.

Finally, there are packaging distributors, such as Industrial Packaging. While we would love to get your business, we may or may not be the right choice for your needs.

Many people will choose a packaging distributor as a shrink-wrap vendor. They do this because distributors sell multiple film brands and film types. Having a diverse product line means they can help you choose the right one for your needs.
