Features of 1:BOPP film bags
BOPP film is a very important flexible packaging material, the application is very extensive. BOPP film colorless, odorless, tasteless, non-toxic, and has high tensile strength, impact strength, rigidity, strong toughness and good transparency. BOPP film surface can be low, glue or printing before the need for corona treatment. However, BOPP film after Corona treatment, has a good printing adaptability, can be color printing and get a beautiful appearance effect, so commonly used as composite film surface material.
BOPP films can be combined with a variety of different materials to meet special application needs. Such as BOPP can be with LDPE (CPP), PE, PT, PO, PVA and other composite to obtain a high degree of gas resistance, moisture resistance, transparency, high, low temperature, cooking and oil resistance, different composite membranes can be used in oily food, delicious food, dry food, impregnated food, a variety of cooking cooked food, monosodium
2:PE Film BagFeatures of:
High Density polyethylene (HDPE) Film: Density of 0.94~0.965g/cm3, thickness is generally more than 0.03mm, its heat resistance, mechanical strength than LDPE film better, tensile elongation is small, poor transparency, the use of front printing, mainly used as vest bags, garbage bags and lining bags.
The printing adaptability of polyethylene (PE) Film: Polyethylene (PE) film, especially low density polyethylene (LDPE), its ductility is large, it is difficult to control overprinter accuracy, the adhesion fastness of oil to is poor, the surface corona treatment must be carried out before printing. Make its surface tension reach 0.038~0.040N/m.
