Kaid plastic films can generally be divided into four categories based on material properties: low-density polyethylene film, high-density polyethylene film, ultra-thin PE film, and environmentally friendly recycled economical PE film. Low-Density Polyethylene Film (LDPE): Generally produced by blow molding and cast film processes. Cast polyethylene films have uniform thickness but are rarely used due to their higher cost. Blow-molded polyethylene films are made from blow-molding grade PE granules and have wide applications. Low-density polyethylene film is a semi-transparent, glossy, and relatively soft film with excellent chemical stability, heat sealability, water resistance, moisture resistance, and cold resistance, and it can withstand boiling. High-Density Polyethylene Film (HDPE): Commonly known as low-pressure polyethylene. Compared to LDPE and LLDPE, it has higher temperature resistance, oil resistance, steam permeability resistance, and environmental stress crack resistance, mainly used in areas such as home appliance packaging bags. Ultra-Thin PE Film: Its appearance is similar to LDPE, but with slightly poorer transparency. However, it has good surface gloss, low-temperature toughness, high modulus, resistance to bending and stress cracking, and better impact strength at low temperatures. It is seldom used alone and is generally blended with LDPE to produce film products that have the performance of LDPE, penetrating almost all LDPE market applications. Environmentally Friendly Recycled Economical PE Film: Odorless and non-toxic, it can be widely used in the production of low-temperature frozen packaging products and has good moisture resistance. Kaid plastic films are categorized as above. We hope this information can help you.
