To Avoid the Yellowing Of Pet Sheet, Here are Some Tips

PET sheet is a thermoplastic and environmentally friendly plastic product that is widely used in packaging for cosmetics, food, electronics, toys, printing and other industries. Many downstream customers of PET sheet manufacturers will respond to a problem, that is, the product yellowing problem, there are no additives to solve this problem?

PET sheet is also known as polyester rigid film, its trim and scrap can be recycled, PET products with no crystal point, high transparency, good gloss, impact resistance, etc., is a newly developed material, which has excellent toughness, high strength, good transparency, coupled with strong recycling performance, is currently sought after by many manufacturers.

However, many PET sheet manufacturers encounter problems such as yellowing of the product and failure to achieve transparency in the production process, which directly affects sales. To solve this problem, we suggest adding yellowing whitening agent in the production process. In PET sheets, the amount of yellowing whitening agent added is very small, only 0.02%-0.05% of the amount needs to be added, and the whiteness value and brightness value of the product will be improved a lot.

In addition, the yellowing whitening agent has good weather resistance, we all know that ultraviolet light is the culprit of yellowing and fading, the yellowing whitening agent can absorb ultraviolet light, effectively improve the service life of the product, even if the long time use, the product will not appear yellowing and fading.

Add the yellowing whitening agent sheet, not only the appearance of improved, for PET sheet manufacturers is also greatly reduced production costs, after all, PET sheet recycling performance is relatively strong, in the absence of raw materials, many manufacturers will use recycled materials for production, and the addition of yellowing whitening agent in the recycled materials, the appearance of the products made and new materials are no different.
