Product introduction

bopp Thin film manufacturer

The production of BOPP non-adhesive film is to make the melt of high molecular polypropylene into sheet or thick film through a long and narrow die, then stretch it in two vertical directions (longitudinal direction and transverse direction) simultaneously or step by step in a special stretching machine at a certain temperature and a set speed, and then make it into a film after proper cooling or heat treatment or special processing (such as corona, coating, etc.).
BOPP special film for non-mucous membrane
Introduction of BOPP non-adhesive membrane products
Commonly used BOPP films include: ordinary biaxially oriented polypropylene, heat-sealed biaxially oriented polypropylene, cigarette packaging film, biaxially oriented polypropylene pearlescent film, biaxially oriented polypropylene metallized film, extinction film, etc.
Characteristics of BOPP special membrane for non-mucous membrane
The surface energy of BOPP non-adhesive film is low, so corona treatment is needed before gluing or printing. After corona treatment, BOPP film has good printing adaptability and can be overprinted to get beautiful appearance, so it is often used as the surface material of composite film.
BOPP film can be produced by tube membrane method or flat membrane method. The properties of BOPP special films for non-mucous membranes obtained by different processing methods are also different. The BOPP film produced by the flat film method has higher tensile ratio (up to 8-10), so its strength is higher than that of the tube film method, and its thickness uniformity is also better.
BOPP can be compounded with many different materials to meet special application needs. For example, BOPP can be compounded with LDPE(CPP), PE, PT, PO, PVA, etc. to obtain high gas resistance, humidity resistance, transparency, high temperature resistance and low temperature resistance, cooking resistance and oil resistance. Different composite films can be applied to the packaging of oily food, rare food, dry food, soaked food, various cooked foods, MSG, pancakes, rice cakes, etc.
