Plastic foam box is a good packaging material, it can not only keep the product dry and sealed, but also make the product more beautiful.
1. Features of Eva box
Eva box is a resin material with good toughness and water resistance. It is widely used in the manufacture of all kinds of packaging containers, mechanical equipment parts, etc. eva case foam: EVA Foam board is made of special processing technology. It has excellent wear resistance and is not easy to rust. Low density factor makes it easy to install and remove; The interior is filled with high quality glass fiber, forming a strong and beautiful appearance; Sound absorption and noise reduction effect is remarkable; Good sealing performance; Not easy to breed mold, thus extending the service life. Glass fiber reinforced plastic film: high strength, high strength composite material made of high purity quartz sand, with good strength, plasticity and impact resistance; It has good thermal insulation effect, and can effectively prevent heat loss, improve heating and cooling efficiency; Light weight, easy to carry; Non-toxic and harmless, will not cause human allergic reaction; No radiation pollution, meet the requirements of environmental protection.
2: Eva box foam material characteristics
Eva box foam plastic material has good wear resistance and impact strength, widely used in construction, auto parts, industrial products and other fields. It also has strong corrosion resistance, high heat resistance, not easy to aging and so on. Therefore, Eva box foam plastic materials have been widely used in many industries. For example: in the automobile industry, the frame, transmission housing, engine housing have used EVA foam resin; In food packaging, cans, bottle caps, yogurt box covers also used EVA foam material;
3: Use method of Eva carton
Eva carton is a new type of foam plastic, it has the advantages of lightness, softness and good durability. At present, there are many different types of EVA resin products available on the market. Generally speaking, Eva boxes can be manufactured using specific kinds or sizes of materials as required. For small projects, it is recommended to use a high strength glass fiber reinforced wooden box or glass fiber reinforced steel box. If you need more space to hold items, you should consider using composite housing. In addition, to ensure structural strength and durability, avoid making them into hollow or open boxes. The correct use of EVA resins and the knowledge of how to install and use these materials can greatly improve the efficiency of engineering operations. First, balance should be maintained during transportation. Secondly, to ensure that the container is not subjected to external forces, so as not to crack. Handling should also be handled lightly to prevent damage to fiberglass materials. Finally, after the installation is complete, be sure to test whether the pressure is intact.
4: Application of EVA resin in products
EVA resin is a transparent material that can be made into plastic foam in a variety of shapes and sizes. It has excellent heat resistance, chemical corrosion resistance and impact resistance, so it is widely used in industrial products. Eva box plastic foam box, mainly composed of three layers of film material: the outer layer is foamed film; The intermediate layer is polyurethane rigid foam; The inner layer is polyethylene foamed film. Fiberglass foam is widely used in automobile accessories, furniture decoration and other industries because of its light texture and easy processing. Glass fiber reinforced composite material (GFRP), also known as glass cloth, refers to the glass fiber woven into a net and polymer composite network structure. Glass fiber fabric specially designed, can not only prevent thermal expansion and cold contraction, but also adjust the volume shrinkage rate within a certain range, so that the product has good strength, stiffness and toughness. Glass fiber reinforced composite materials are widely used in aerospace, shipbuilding, architectural decoration, furniture manufacturing and other fields.
