Nylon 6 film material is a good oxygen barrier and puncture resistant film material. However, the current nylon 6 film material supplied on the market is not synchronized with the LLDPE/LDPE due to the change of viscosity with the processing speed, resulting in low productivity of the multilayer oxygen barrier film, large product loss (such as no nylon material on the edge), and poor appearance quality. Good (if the film has a curl or ripple). Due to the large investment in thin-film production equipment, manufacturers of multilayer oxygen-barrier films are eager to find a new type of nylon 6 film material that can efficiently separate oxygen and greatly increase production efficiency. For this reason, after years of hard work, DSM recently introduced a new generation of high-tech nylon 6 film material Akulon(r) XP to the market.
Akulon(r) XP can be produced in a variety of processes. In the casting production process, the distribution and thickness of different material layers are more uniform, the necking phenomenon is small, so that the cutting amount of the waste material is greatly reduced; the production speed of the nylon film can be increased by 100%, and the energy consumption can be reduced by at least 50%. .
In the co-extrusion process (multi-layer paper-plastic coating), the stability of the film has been greatly increased, the necking phenomenon has been greatly reduced, and the production speed can be increased to 1,100 m/min. When Akulon(R) XP reduced the adhesive thickness of multilayer oxygen barrier films by 50%, the stability and production speed of the films were not affected at all.
As for the blow molding process, the stable film layer structure enables the manufacturer to design and manufacture unique film products; Akulon(r) XP can reduce the adhesive thickness of the multilayer oxygen barrier film by 50%; when the nylon layer mainly prevents tearing When effected, the thickness can be reduced by 50%; due to the reduction of the film thickness, the production speed of the film can be greatly improved.
Folding Sofa is also called sofa bed. It can be used both as a sofa and as a bed. It is necessary to place a folding sofa at home as the living area in our households becoming increasingly compact. With diverse designs and sizes, folding sofa has been proven to be a functional furniture item that is beautiful, comfortable and practical.
