PVDC Coated Films Manufacturers
PVDC coated film is a different base film (PET/BOPP/BOPA) coated in one layer or multilayer PVDC( Polyvinylidene chloride), to get the high barrier property. It has excellent barrier performance that can reduce the big amount of oxygen transmission, this makes PVDC ideal for household wrap and food, medical, and pharmaceutical packaging to extend shelf life. PVDC also is highly resistant to many chemicals including grease and oil and has good performance in aroma retention, freshness retention, oil resistance, etc. And also has good printing and composite performance, It can have double-sided heat sealing performance (heat sealing strength ≥0.8N/15mm) as required.
PVDC( Polyvinylidene chloride) is a clear and flexible synthetic thermoplastic produced by the polymerization of vinylidene chloride, a transparency packaging material with good barrier properties, It is optically clear with a high degree of gloss and has outstanding oxygen and moisture barrier properties comparable to metalized films.
PVDC has had a long history of its usage, since the first industrialized production of DOW Chemical in the United States in the 1930s, PVDC has become synonymous with high barrier, and the packaging industry even calls it the “queen” of high barrier materials.
The PVDC-coated film can be easily extruded and laminated. It is also microwavable and printable using common ink systems.
Coated film refers to a type of plastic film that has been coated with a layer of material, such as a metal, to provide specific properties, such as improved durability, reflectivity, or adhesion. The coating material and the thickness of the coating can vary depending on the desired application. Some common applications of coated film include packaging, solar panels, and protective coverings for electronics.
PVDC (Polyvinylidene Chloride) coated film is a type of flexible packaging material that is produced by coating a polymer film with a layer of PVDC. The PVDC coating provides the film with excellent barrier properties, making it ideal for packaging applications where protection from moisture, gases, and aromas is important. Some common uses of PVDC coated film include packaging for food and pharmaceuticals, as well as for medical and industrial products.
The PVDC coating process typically involves the application of a PVDC resin onto the surface of the film, which is then cured and cross-linked to form a continuous and dense barrier layer. The resulting film has a high degree of resistance to moisture, gases, and aromas, and it can also provide protection from UV light, depending on the thickness of the PVDC coating. Additionally, PVDC coated film can be produced in a variety of thicknesses, making it adaptable to different packaging requirements.
The characteristics of PVDC coated film
Barrier properties: The PVDC coating provides excellent barrier protection against gases (such as oxygen, carbon dioxide, and moisture) and liquids, making the film ideal for food packaging and other applications that require protection from the environment.
Transparency: PVDC coated film is transparent, allowing for good product visibility and easy inspection.
Toughness: The film is strong and durable, making it resistant to tearing, puncturing, and other forms of damage.
Sealability: PVDC coated film is heat sealable, allowing for the creation of airtight packages that are difficult to open and tamper with.
Chemical resistance: The film is resistant to a wide range of chemicals and oils, making it suitable for use in packaging for products such as cosmetics and pharmaceuticals.
Low permeability: The PVDC coating provides low permeability to gases and liquids, preserving the freshness and quality of packaged products.
