PLAM ex developed a new film extrusion technology

in a newly developed extrusion system, plam ex combines casting and finishing processes

the packaging materials used for volatile foods such as meat, sausage, ham and cheese products should provide a separation layer of smell and fragrance, with moisture to prevent the contents from drying out, grease resistance, and neutral taste; Optical properties, such as transparency and gloss, can be printed and easy to label; Mechanical properties such as toughness and bending strength, thermoforming and sealability can be processed at high speed on modern packaging machines

Jinan experimental machine factory Jinan new era Gold Testing Instrument Co., Ltd. recently developed many experimental machine models

in previous years, the market was dominated by polyamide polyethylene double-layer film. At present, it tends to five to seven layers of composite materials, and in fact, the market can even find products with nine to eleven layers of film. Most of these multilayer films are produced by bimetallic extrusion. Bimetallic extrusion technology is increasingly used in the direct production of three to seven layer composites. Considering the growing market demand for parallel and serial interfaces, polyethylene materials for film production need to be developed. Therefore, high viscosity PA6 products are developed, which are mainly used for flat films with a thickness of 25 ~ 150mm, especially for pulling out polyethylene layers with a thickness greater than the required thickness; Medium viscosity polyethylene 6 varieties, mainly used for manufacturing thin films rolled by quench rolls, with a thickness range of 15 ~ 60mm

the special needs of these polyethylene 6 varieties lie in the aspect of bimetal extruded flat film, because their main low-density polyethylene varieties used for this purpose are similar in rheology. Copolyamide is almost limited to the production of bimetallic extruded blown films. The solidification and crystallization rate of the copolymer in the cooling stage is significantly lower than that of pure polyethylene 6 products. Most isolation films are produced by tape casting film extrusion. The main reasons include high productivity, film quality standards can be controlled, film properties can be affected by process parameters, and the possibility of material combination into a specific film. In order to meet the requirements of polymer review 1. Whether the conditioning baffle of downwind circulation can open the huge variety and thickness range of normal composite materials (15 to 350 microns and above), plam ex combines casting and finishing in a newly developed extrusion system
