When initially adopting vacuum skin packaging machines to package products for skin packaging, it is essential to first understand the various types of skin packaging film materials. Based on the characteristics and production requirements of the packaged products, as well as considerations for skin packaging costs, the most economical and suitable skin packaging film should be selected. Different skin packaging film materials possess corresponding characteristics. Having a deeper understanding can help you choose the right skin packaging film and avoid detours, quickly achieving the desired skin packaging effect. Today, Fengyuan Skin Packaging Network Information Department will summarize the types, characteristics, and selection principles of skin packaging film materials.
The mainstream types of skin packaging film materials mainly include PVC, PE, PET, and surlyn,. Let's discuss them one by one.
PVC skin packaging film (PVC skin film) is the most cost-effective skin packaging film. Its advantages include high transparency, low cost, and good stiffness. However, its disadvantages are its poor stretchability, which makes it easier for irregularly shaped products to puncture the film during packaging, affecting the appearance of the skin packaging. It also cannot withstand low temperatures and is prone to brittleness, which can lead to the loss of protective effectiveness for products. It is mainly used for packaging low-value hardware products, and is mainly used in developing or underdeveloped countries such as China, Vietnam, Thailand, and Africa.
PE skin packaging film belongs to the soft type of skin packaging film. Its advantages include excellent toughness, low-temperature resistance, and excellent product protection performance. It also has low cost and significantly better stretchability than PVC skin packaging film. There are various types available, ranging from non-sticky, low-sticky, medium-sticky, to high-sticky. Functional additives can be added to make the skin packaging film antistatic, rust-proof, UV-resistant, biodegradable, and available in various colors. Its disadvantage is that its transparency is slightly lower compared to PVC skin film and surlyn, film, as well as PET skin film. It is mainly used for packaging hardware products, lighting fixtures, screw packs, mold parts, medical supplies, brake pads, radiators and other automotive parts, circuit boards, magnetic cores, etc.
PET skin packaging film (PET skin film) is a rigid type of skin packaging film with excellent stiffness and protective properties. It has extremely high transparency and excellent stretchability, ensuring perfect skin packaging effects. It is particularly suitable for large, irregular, and heavy products.
Surlyn, film (Dupont Surlyn, skin packaging film) is the most high-end type of skin packaging film, offering numerous advantages. It has extremely high transparency, providing excellent visual display effects. Its excellent stretchability allows it to completely conform to the shape of the product during vacuum skin packaging, resulting in a perfect skin packaging effect. It can also withstand low temperatures and offers excellent protective performance. Its only drawback is its relatively high price. It is mainly suitable for packaging high-end hardware products such as saw blades, drills, and other hardware tools, decorative hardware, furniture hardware, salmon and other seafood, cold fresh meat such as beef and lamb, and other food items.
