EVA packaging is widely used in: electronic digital, electrical appliances, hardware, plastic, cosmetics, computers, toys, gifts, watches, tea, tobacco and alcohol industries. All products have passed the international quality certification system and environmental protection international certification, can be directly exported to the world.
Many of you may not be familiar with the word EVA, but what is EVA?
EVA is a new type of compound packaging material, which has the following characteristics: water resistance: closed bubble structure, no water absorption, moisture-proof, good water resistance. Corrosion resistance: resistant to seawater, oil, acid, alkali and other chemicals corrosion, antibacterial, non-toxic, tasteless, pollution-free. Processing: no joints, and easy to hot pressing, cutting, gluing, fitting and other processing. Shockproof movement: high resilience and tension resistance, strong toughness, with good shockproof/buffering performance. Heat preservation: Excellent heat insulation, heat preservation and cold protection and low temperature performance, cold resistance and exposure. Sound insulation: airtight bubble hole, sound insulation effect is good.
EVA products application scope: electronic products, household appliances, hardware tools, toys, crafts, tourism products, cultural articles, cosmetics, etc.
The types of EVA products include: EVA game package, EVA camera package, EVA headset package, EVA camera package, EVA kit, EVA medical package, EVA CD package, EVA electronic package, etc.
Due to the characteristics of EVA material itself, the bag made of EVA material has the advantages of good buffering, earthquake resistance, heat insulation, moisture-proof, chemical corrosion resistance, and non-toxic, non-absorptive. And the fabric choice is diversified, the shape is easy to shape, the appearance is fashionable and noble, the accessories can be adjusted at will, and the mesh bag is added to strengthen the personalized and diversified function of the bag.
The main production process of EVA bag is introduced:
1. Composition of fabric -- It is made of fabric, EVA and lining material after fitting
The choice of fabric is diverse, can be Oxford cloth, PU, hibber leather, etc., the base material can be velvet, good product cloth, etc. EVA types can also be subdivided by its thickness and hardness, commonly used are 5MM, 6MM, 7MM, the higher the thickness, the harder the product.
2, the main process - hot pressing molding
After the fabric is fitted, it is cut. After 40 degrees to 70 degrees of heating, into the hot press, the shape can be immediately out. Of course, the corresponding mold should be prepared before this. This heating temperature is also very particular, this is not much to introduce;
3. Printing process
There are many kinds of printing supported, such as general printing, screen printing, thermal transfer printing, rust printing and so on. In addition, there are gravure printing and embossing. This special process is because it is engraved on the mold, and the effect will come out together when forming.
