How to clean up the waste of the manufacturer of plastic tray

Blister tray material is one of the first things required for the production of packaging, but how these packaging materials are produced I think not many people understand. This article analyzes the use of blister packaging materials and the production process.

First, resin matrix composite materials

There are many kinds of polymer composite materials with resin as matrix, such as various fibers, granules or films. Such as adding conductive fiber composite into conductive functional materials, absorbing functional materials, adding ceramic, glass fiber and carbon fiber composite reinforcement materials, or different resin film multilayer composite into composite materials, etc., its application field is very wide; More than 30 kinds of fibers are commonly used in reinforced fiber composites. In packaging has been widely used in the main organic layer composite, co-extruded composite, mixed composite and other types of composite materials.

Second, the development trend of resin matrix composite materials

The first is to improve the composite technology, improve the properties and functions of composite materials; The second is to select appropriate materials and better technology to reduce the cost of composite materials; The third is to develop new varieties, such as structured materials, functional materials, molecular composite materials, ecological composite materials and so on.

Third, functional polymer materials

The new varieties of functional polymer materials mainly fall into several categories :(1) electrical functional polymers such as conductive materials; (2) optical functional molecules such as photoconductive materials, graded refractive index polymers; (3) Chemical functions such as catalytic materials, adsorption materials; (4) magnetic functions such as magnetic polymer materials; (5) Separation membrane and oxygen-rich membrane polymer materials in mechanical functional mass transfer functional materials; (6) Biological functions such as biomedical polymer materials, biodegradable materials (heat-shrinkable films), heat-resistant polymer materials, heat-sensitive color-changing materials; (7) Intelligent polymer materials (such as PSA, polynurofen, polyaniline) and so on.

Fourth, surface modified materials

There are many kinds of modern modified materials, including metal, non-metal, ceramic, plastic and multi-compound. The packaging industry uses relatively more new surface modified materials. For example, in order to improve the condensation performance of the packaging plastic film, the true air phase deposition (PVD) technology is used to "coat" a thin layer of aluminum film on the plastic surface, as well as silicon oxide film; The plastic film was treated by laser scanning. The surface modification of electrolytic iron foil is carried out to strengthen the material properties. Common secondary pollution in landfills.
