Product Common Packaging Materials Introduction

[China Packaging Network News] We have seen many products in our lives, and we also know a lot about the packaging of various products. However, do you know what's in the packaging?

First, paper packaging materials

In the whole process of packaging design development, paper packaging materials, as a universal packaging material, are widely used in production and life practices. The paper material has low cost, is suitable for large-scale mechanized production, and has good moldability and foldability, is suitable for exquisite printing, and has the advantages of recyclable, economical and environmental protection.

1, kraft paper

The kraft paper is tough and inexpensive and has good folding and water resistance. Mostly used for making shopping bags, envelopes, cement bags, etc., also used for food packaging paper.

2, coated paper

Coated paper is mainly made of high-grade raw materials such as wood and cotton fibers and is divided into single copper and double copper. Applicable to multi-color printing, bright colors after printing, rich levels change. It is commonly used in the production of handbags, business cards and books, magazine covers.

3, white paper

Whiteboard paper is hard and thick, with good standing strength, surface strength, folding resistance and printing adaptability. It is suitable for packaging boxes and liners.

4, corrugated paper

Corrugated paper has the advantages of light sturdiness, strong load and pressure resistance, shock resistance, moisture resistance, etc., and low cost. Single-sided corrugated cardboard is generally used as a protective layer for packaging of goods or lightweight cagging or padding to protect products from vibration or impact during storage and transportation; three- or five-layer corrugated cardboard is used for the sale of manufactured goods. Packaging; seven or eleven layers of corrugated paperboard mainly for the production of mechanical and electrical products, furniture, motorcycles, large appliances and other packaging.

Second, plastic packaging materials

Plastics have good water resistance, moisture resistance, oil resistance, and insulation, and they are lightweight, colorable, and easy to produce. They can be molded in a variety of shapes and can be adapted to printing. Their raw material sources, low cost, and excellent performance have become nearly 40 percent. The world's fastest growing packaging material is one of the most important packaging materials in modern sales packaging.

1. General plastic

Common packaging common plastic components are mainly polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS).

2, foam plastic

Foam plastic, also known as porous plastic, has excellent impact resistance and vibration resistance, low thermal conductivity, low water absorption, low moisture absorption, chemical stability and other characteristics, often used in product cushioning packaging materials.

Third, metal packaging materials

Metals are widely used in industrial product packaging, transportation packaging and sales packaging. Excellent mechanical properties, high strength, excellent overall protection performance, special metallic luster, easy printing decoration.

1, steel packaging

Compared with other metal packaging materials, steel sources are abundant, energy consumption and cost are low, and they have good plasticity and ductility.

2, aluminum packaging

Aluminium is light weight, has good ductility and corrosion resistance, is not easy to rust, has long-lasting brightness, and is easy to print, process and recycle. Aluminum is mainly used for sales packaging, the most common such as cans.

Fourth, glass, ceramic packaging materials

Glass has a high degree of transparency, impermeability and corrosion resistance, non-toxic and tasteless, stable chemical properties, lower production costs and other characteristics, can be made into a variety of shapes and colors of transparent and translucent containers.

Ceramics have a good chemical stability and thermal stability, can resist the erosion of various chemicals, high temperature, rapid changes in hot and cold will not affect the ceramics, is an ideal food, chemical packaging containers.
