            Plastic bottle caps have many advantages, but some people worry about whether it is safe. What material is made of plastic bottle caps? Of course, different liquids require different material plastic bottle caps. Under normal circumstances, plastic bottle caps are made of PP and PE materials. PP materials: mostly used for gaskets and caps of gas beverage bottle caps, heat resistance without deformation, high surface strength, good chemical stability, disadvantages are poor toughness, easy embrittlement under low temperature conditions, and poor oxidation resistance. Wear-resistant. Bottle caps made of this material are mostly used for packaging of fruit wine and carbonated drinks.

            PE materials: mostly used for hot-filled bottle caps and aseptic cold-filled bottle caps. This material is non-toxic, has good toughness and impact resistance, and is easy to form films. Good, the disadvantage is that the molding shrinks greatly and the deformation is severe. Many vegetable oils and sesame oil in glass bottles are on this market. These two materials are environmentally friendly materials, there is no toxic plastic, and the material of plastic bottle caps is safe. The processing and molding process is relatively safe.
