Types and advantages of PP plastic film

PP plastic film homopolymer is the most widely used general-purpose grade. It contains only propylene monomer in semi-crystalline solid form. Key application areas include packaging, textiles, healthcare, plumbing, automotive and electrical applications. The PP plastic film copolymer family is further divided into random copolymers and block copolymers produced by the polymerization of propylene and ethane: PP plastic film random copolymers are polymerized from ethylene and propylene. It features ethylene units, usually up to 6% by mass, randomly added to PP plastic film chains. These polymers are flexible and optically clear for applications requiring clarity and products requiring good appearance. In the PP plastic film block copolymer, the ethylene content is relatively large (between 5-15%). It has regularly arranged comonomer units. Thus, the regular pattern makes thermoplastics tougher and less brittle than random copolymers. These polymers are suitable for applications requiring high strength, such as industrial use. PP plastic film, impact copolymer - propylene homopolymer contains a blended propylene random copolymer phase with an ethylene content of 45-65%, called PP plastic film impact copolymer. It is suitable for parts that require good impact resistance. Impact copolymers are primarily used in packaging, household goods, film and piping applications, as well as in the automotive and electrical sectors. Expanded PP plastic film - is an ultra-low density closed cell foam. EPP is used to produce three-dimensional foamed polymer products. EPP beads have a high strength-to-weight ratio, excellent impact resistance, thermal insulation, chemical resistance and water resistance. EPP is widely used in everything from automobiles to packaging, from construction products to consumer goods and more. PP plastic film terpolymer - it consists of propylene segments linked by ethylene and butane (comonomers) monomers that appear randomly in the polymer chain. PP plastic film terpolymer has better transparency than PP plastic film homopolymer. In addition, the addition of comonomers reduces the crystallinity uniformity in the polymer, making it suitable for sealing film applications. PP Plastic Film, High Melt Strength (HMS-PP) – It is a long chain branched material that combines high melt strength and elongation during the melting stage. PP-HMS grades have the characteristics of a wide range of mechanical properties, high thermal stability, and good chemical resistance. High molecular weight PP plastic film (HMS-PP) is widely used in the production of flexible, low-density food packaging foams as well as in the automotive and construction industries.
