Nanjing Suminoe Precision Co-extruded barrier composite films are usually made up of a combination of barrier plastics, polyolefin plastics (moisture-proof plastics, generally also used as heat-sealing layers) and adhesive resins, which are described as follows.First, the barrier resinAt present, th

Anilox Coating, develops various types of in-line coating equipment in accordance with market demand.Sheet online coating unit, the use of coating can be used to treat the surface of the sheet, can achieve permanent anti-static, anti-fog and other special requirements. The special sheet is made of n

The barrier properties of plastic films are greatly influenced by environmental factors. The barrier properties of plastic films are usually influenced to a greater or lesser extent by the ambient temperature. Generally speaking. The higher the temperature of the same film, the greater the permeabil

I. Factors affecting the performance of vapour plated silicon oxide barrier packaging filmsVapour plating base film, vapour plating method, vapour plating conditions as well as the composition of the vapour plating coating and the thickness of the vapour plating layer may have a great impact on the

All films made from thermoplastics share a common problem: special production techniques must be used to achieve a uniform thickness. Unlike extruded tubes and sheets, extruded films can have large variations in thickness if special steps are not used. Even now, the quality of the films produced in
