PROTECTIVE FILMS

What Are the types of Plastic Films?

Dec. 07, 2021

PVC

Vinyl film, also known as polyvinyl chloride or PVC, is a versatile, inexpensive thermoplastic with good dimensional stability, good impact strength, and excellent weather resistance, which is easy to die-cut and can be printed using traditional screen and offset printing methods. Depending on the composition, it can be clear or matt, colored or white, rigid or flexible. The flexible vinyl film has good barrier properties to oils and greases but is oxygen permeable. It also has good puncture resistance and good adhesion and excellent transparency.

 

Nylons

Polyamide (PA), also known as nylon, is a transparent and printable thermoplastic with a relatively high melting point, excellent strength and toughness, and good oxygen barrier properties. It is also resistant to scratches, punctures, and bending cracks and will not dissolve or absorb grease, oil, and acidic foods. These properties make PA ideally suited for use in conventional and microwave cooking applications. The two most common types are cast nylon films and biaxially oriented nylon films. Biaxially oriented polyamide or BOPA films can be used in a wide range of applications, especially where high gas barrier properties are required. It is often considered a specialty film due to its high price compared to PVC films, PE films, and PP films.

PET Protective Film

PET (BOPET)

Polyester film is a high-performance, crystal-clear thermoplastic made from polyethylene terephthalate (PET). Compared to other common plastic films, PET film has high tensile strength, excellent dimensional stability, low moisture absorption, and good retention of physical properties over a fairly wide temperature range. It also has excellent UV resistance and excellent electrical properties, as well as good optical transparency. It is often considered a specialty film due to its high price relative to PVC, PE, and PP films.

 

DC transmission

Polyvinylidene chloride (PVDC) is a synthetic thermoplastic made from the polymerization of vinylidene chloride. The most common type is a biaxially oriented film. PVDC has excellent oxygen and moisture barrier properties comparable to aluminum foil and is resistant to a wide range of chemicals including grease and oil, making it ideal for food and pharmaceutical packaging applications with extended shelf life. It can also be printed using common ink systems and offers excellent bond strength, high heat resistance, and low water absorption. PVDC is often used as a coating for other films to improve their gas barrier properties.

MPE

Metallocene polyethylene or mPE is a low-density polyethylene made using metallocene catalysts. This technology gives the resin very pure and consistent properties. mPE film has a fast thermal adhesion similar to that of EVA, allowing for fast sealing. It has excellent puncture resistance and oxygen permeability as well as good tensile strength at break, much stronger than ordinary polyethylene. For many applications, mPE is a suitable alternative to PVC and EVA.

 

ULDPE

Ultra Low-Density Polyethylene or ULDPE is a soft and very flexible thermoplastic often used for very special film applications such as stretch wrapping, food packaging, health, and hygiene. Compared to LDPE, ULDPE has higher low-temperature flexibility and resistance to bending and cracking, making it ideal for applications requiring excellent optical properties and high tear resistance. However, (unmodified) ULDPE has poor UV resistance and barrier properties, with the exception of water.
