            There are a lot of goods on the market now, there are many bottles, cans, plastic bottles, glass bottles and many other bottles. Of course, the bottle must be used with a cap. There are many types of caps, including stainless steel caps, wood caps, and disposable plastic caps. The hottest thing is the disposable plastic cover, which is because the disposable plastic cover is full of highlights. First of all, disposable plastic covers are simple to make and use in a short time; secondly, plastic covers are a waste of resources, but they actually save resources and steel indirectly; finally, there are many types of plastic plastic covers. , The full highlights of disposable plastic caps can be perfectly combined with many types of bottles.

            Plastic bottle caps have many advantages, but some people worry about whether it is safe. What kind of material are plastic bottle caps made of? Of course, different liquids require plastic bottle caps of different materials. 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, non-toxic, and relatively safe to process.
