At present, Europe and the United States advanced countries have been continuously emphasis on environmental and health requirements, without solvent dry compound, composite extrusion and co-extrusion composite film is gradually replaced by solvent dry compound.
Along with our country food hygiene supervision agencies merged with medical health supervision institutions, on health performance requirements of packaging materials in the future will be more strict, flexible packaging composite materials in China will happen structural adjustment, step by step with international practice, it's for extrusion composite provides a larger market.
Abroad, composite extrusion equipment is to develop in the direction of multigang, co-extrusion.
In order to adapt to the multilayer structure of composite products, improve production efficiency, composite extrusion machine generally adopts multiple series extruder and composite structure, the one-time production of products, due to the emergence of various functional plastics raw materials, composite extrusion are also developed to the direction of co-extrusion composite extrusion, it is to use the workings of a composite extrusion, and extrusion die head is multilayer co-extrusion die head, several extruder respectively by using different materials to a total of extrusion, high compound strength, in order to achieve the function of the composite material or giving, some products can greatly reduce the cost.
Extrusion composite plastic resin have been introduced, the composite extrusion to functionalization.
In addition to the commonly used various thermal bonding resin, LDPE, PP, is to develop in the direction of other thermoplastic resin, is expected in the near future, composite extrusion of LDPE, LLDPE, PS, PA, PU,
Pu)
电脑(
Polycarbonate)
PVA (
Polyvinyl alcohol)
To mass production, such as functional resin composite extrusion will have greater development.
Composite extrusion technology is also in constant innovation, besides using the new functional materials, all kinds of methods to improve the performance of composite extrusion process has been adopted, such as through process change extrusion membrane molecular polarity or improve the surface of the substrate membrane performance in order to improve the peel strength of the composite extrusion.
In the low level of the composite extrusion, the future development direction of the first is through the equipment and process improvement, improve product performance, to adapt to the demand of the market, expand the scope of use, from the simple packaging on the second floor to multilayer composite packaging, composite extrusion product structural change, in the years to come, will develop the co-extrusion composite extrusion process, the resin material will be given priority to with blending modification, to adapt to the more complex requirements.
Northerners of tetra pak company production line, for example, using the co-extrusion touching someone will EAA Shanghai juji between the aluminum foil and LDPE, increases the peel strength between LDPE and aluminum foil, and to protect and prevent the process of infiltration layer, the use of the LDPE and metal ions, blending material in order to solve the shortage of the pure LDPE.
, heat sealing layer with LDPE and & other
Strong & throughout;
Ion of the blending material can not only improve the heat seal strength and reduces the heat sealing temperature, avoid excessive heat sealing temperature on the quality of the food, the process of change for equipment manufacturers is both a challenge and a rare opportunity.
