Innovative design of extrusion blow molded products

There are a wide variety of types and styles of eExtrusion blow-molded hollow containers come in many varieties and various styles.The containers, and play a very important role in people’s production and life.

Innovative design of packaging containers

Packaging containers mainly refer to plastic packaging containers. With the rapid development of the petrochemical industry and the rapid development of the plastic industry, plastic packaging containers have replaced packaging containers made of metals, glass, ceramics, wood and other materials in many ways, showing a strong vitality. The innovation of these product designs has brought convenience to productiongiven People’s production and life bring convenience and improve people’s quality of life.

1. Features of plastic packaging containers

The advantages of plastic packaging containers are as follows.

①The plastic has low density and light weight, and can be transparent or opaque.

②Easy forto forming process and process, as long as the mold is changed, containers of different shapes can be obtained, and it is easy to mass produce.,
@Packaging effect is good,As package,they work well.They are colorful and easy to color. Easy to color, bright color, Ddifferent types of packaging containers can be made according to needs and will , have better effect.obtain tray
Good packaging effect.

④It has good resistance for corrosion, resistance, acid, and alkali, resistance, oil and impact, resistance, and has good mechanical strength;

Plastic packaging containers also have deficiencies disadvantages.

①Plastics are easy to soften and deform at high temperature, so the use temperature is limited.

②The surface hardness of the container has is low hardness, and it is easy to wear or scratch; under the action of light oxygen and hot oxygen, plastics will degrade, become brittle, have performance depreciation other aging phenomena. the plastic will degrade and become brittle.
Performance degradation and other aging phenomena.

③ Poor conductivity, easy to generate static electricity accumulation, etc.

2. Classification of plastic packaging containers

① Classified according to the nature of the raw materials used, containers mainly includeing polyethylene (PE), polypropylene (PP), polystyrene (PS), and polychloride

Vinyl (PVC), polyester (PET), polycarbonate (PC),etc. and other containers.

②Classified according to container molding methods, containers mainly includeing blow molding, extrusion molding, injection molding, stretch molding, rotational moldingomolding

Type, vacuum moldingforming,and etc.other containers.

③Classified according to shape and use, containers mainly includeing plastic boxes, plastic barrels, plastic bottles, plastic bags, plastic hoses, etc. Plastic packaging containers are generally made by molding, the shape of which depends mainly on the molding method and the mold used. Sometimes the same (or similar) form can also be produced by different methods. For example, hollow containers are generally made by blow molding, but they are also often made by rotational moldingrotomolding (especially extra large containers, small batch containers, or special-shaped containers); turnover boxes are generally made by injection molding, but In some special cases, in order to meet the needs of use, it is made of calcium plastic panels (having the advantages of light weight and low price, but slightly inferior in strength) or molded from pre-expanded polystyrene beads (with special oOutstanding thermal insulation performance and good shock resistance), even made by sheet thermoforming (low cost but limited strength has limited intensity).
