Packaging materials

Packaging materials must be mentioned when learning the applications on packaging because it is the basis of packaging. Only by understanding the characteristics of the various packaging materials, they can be selected to harmonize with the characteristics of the goods themselves. packaging materials can be divided into the following:

Wood packaging materials

The wooden material which is widely used, this is because the wood has a wide distribution, light weight, high strength, elastic and can withstand impulse and vibration, easy processing advantages. However, the unevenness of the organizational structure of the wood packaging materials, susceptible to the environmental impact of the deformation, and has easy decadent, flammable, easy to termite and other shortcomings. The above shortcomings, can be eliminated or reduced if had been properly treated.

Paper packaging materials

Paper packaging materials are the most popular materials, which is inseparable from the unique advantages of the paper. The paper not only has the advantages of easy formation of high-volume production, low prices. It can also be recycled to protect the environment. The paper has a certain elasticity and folding properties are also excellent, with good printing performance, writing, a clear pattern firmly. Therefore, more and more attention has been paid on the paper packaging materials.

Paper packaging materials can be divided to different classifications according to different standards. The following paper the different characteristics can be divided into two types of functional protective wrapping paper and packaging and decoration paper.Functional protective wrappings, such as tough, sturdy kraft paper, corrugated paper, transparent cellophane paper, sulfuric acid paper.

The plastic packaging material has good transparency, light weight, easy to shape, waterproof, moisture resistant and can guarantee the health of the packaging advantages. However, plastic packaging materials easily with static electricity, air permeability, high cost of recycling, waste disposal problems, likely to cause pollution to the environment. Some plastic materials containing toxic additives, it should take the necessary measures to reduce or avoid the damage.

Metal packaging materials

Metal packaging is made ​​of black metal, tin, steel and steel plate, aluminum foil, aluminum and other packaging containers. Such as metal drums, metal boxes, canned tin etc..

Meanwhile, the metal material has a special metallic luster which is easy for printing decorative, decoration design to facilitate the appearance of the goods. However, metal materials with low chemical stability, it is easy to rust, or even a small amount of metal materials may also affect the quality of food.

Glass packaging materials

Glass packaging material has good chemical stability to ensure food purity and sanitation, airtight, it is easy to seal and shape flexible, colorful and crystal decorative effects, has been widely used. There are a wide variety of glass containers according to different criteria. It can be divided into a colorless, transparent bottles, colored bottles and opaque glass opacities according to color; or divided into food packaging, bottles, beverage bottles, wine bottles and so on according to usage. However, glass has a lower resistance to impact, high energy consumption of the financial system and other shortcomings.

Ceramic packaging materials

The ceramic according to the materials used can be divided into coarse earthenware, fine earthenware, porcelain, stoneware. Ceramic packaging materials with high hardness, corrosion resistance performance to heat, water and other chemical media. Different priced goods packaging performance requirements of different ceramics. It mainly used for wine packaging. However, Ceramic packaging material is friable, and the higher cost recovery shortcomings.
