Characteristics of biodegradable foaming shock-absorbing packaging materials

polyurethane, polyethylene foam and other plastics have been widely used in the fields of noise reduction and heat insulation, antifreeze and heat preservation, cushioning and shockproof, high-grade packaging liners and so on. However, because they cannot be degraded after being used and discarded, they cause "white pollution" to the nature

the biodegradable foamed shock-absorbing packaging materials developed by our company can replace polyurethane, polyethylene foam and other plastics in terms of performance and use function, and can be degraded after being used and discarded, participating in the carbon cycle between human and nature, thus eradicating the "white pollution" caused by these products to the nature in the process of curing the samples in the curing box

biodegradable foamed shock-absorbing packaging materials have the characteristics of high starch content and high biological content. In addition to the unique foaming process and advanced and special foaming equipment, their product appearance is basically the same as that of polyurethane and polyethylene foam materials. Above the electronic and electrical products and precision instruments, there are the advantages of pressure testing machines and the detailed introduction of ordinary management of high-end products, such as cushioning, shockproof, noise elimination and heat insulation, antifreeze and heat preservation High grade packing liners and other packing fields have special applications. In particular, the waste will not pollute the nature after use. The landfill can degrade itself in a short time. There is no black smoke and harmful gas during incineration

biodegradable foaming shock-absorbing packaging materials have more advantages in biodegradability as packaging materials. The biological content of this kind of foaming material is more than 60%, which has good biodegradability. Because the surface area of the material is increased to 20-45 times by foaming method, the overall degradation rate is greatly improved after it is used and discarded and enters the waste treatment system (such as incineration or garbage dump). However, because it does not have a biodegradable environment in the packaging box, it will not degrade when used as a packaging material and can meet the use requirements

the product has the following characteristics:

(1) the amount of starch added is generally 40%. If there is a range jump above 40%, it can be controlled at 40% - 80% according to the needs of users

(2) the processability and physical and mechanical properties of the products are as superior as those of ordinary plastics and products

(3) it is time-controlled, denatured, non-toxic and expandable, and the degradation can generally be completed within 200 days

(4) it can save oil resources, reduce the dependence on oil resources and improve China's energy security

(5) disposal after use is suitable for the requirements of environmental protection
