The basic knowledge of BOPP

1. The development of BOPP In 1955, the polypropylene was synthesized of Ziegler one of a catalyst by the Italian. In 1958, the biaxial oriented polypropylene had been promoted; it is advancing rapidly now, BOPP is above 50%. This type of film has the outstanding function and extensive rang of application. The biaxial oriented film production line made by Bruckner is prominent. It was adopted by many film manufactures. 2. The usage of BOPP It has the outstanding function of transparency, non-toxicity, mechanical strength, so it is used in paint, lamination, tape and so on. In recent years, with the more mature and innovation of the film technology, many new types of film which expand the range of application have been developed, such as pearl film, matt film, vacuum aluminum plating film, laser transfer film and so on. In using of these types of film we should pay attention to the corona treatment value. Its using surroundings should be kept clean, a certain temperature and humidity, and the influence of static should be decreased. Film should be matched before printing. 3. BOPP storage We should stave off high-tempo and high-humidity envrioment  to store the film for long time. It can’t be stored over six months. It must be set upright to prevent distortion, and it can’t be stored over tow layers. 4. The notice of BOPP Before consignment, the film must be treated with aging treatment, so the physical properties, mechanical strength and surface tension can be stable. It's the best to use the film at the proper time. The shelf life can’t exceed six months. With the time going on, the surface tension of film will decline when preserving too long time, so it may influence normal usage. 5. New type BOPP introduction Our company has developed four new types for the sake of market demands. They are laser embossed material film, laser transfer material film, anti-fog film and laser embossed film.　They are sunshine-brand. Laser embossed material film is a base material of anti-fabricate. This type film has the outstanding function of being-embossed. For example, it has clearly embossed effect, transparency and good imaging. It can be used to pack famous brand-name commodity extensively. Laser transfer material film is an environment-protecting type. The design on this type film can be transferred to other objects, and it can be used repeatedly. It has the outstanding function of clearly embossed effect, transparency, good imaging, and transfer completely, even thickness, steady-going quality, safe and health. It can be used to pack commonplace and brand-name commodity extensively. Anti-fog film has been wildly used in Japan and other developed countries. This type film has the outstanding function of anti-fog, transparency, double sides heat-heal, fusion, paint permitted, even thickness, steady-going quality, safe and health. It can be used to pack vegetables, fruits and any other eatable foods, displayed in supermarkets, it can be attract more visitors.Laser embossed film is made of laser embossed material film, the surface of the film is embossed to reflect various designs, it has the anti-fabricated function, and the design can be manufactured by your request.
