Chemical packaging drums are light and not fragile. Chemical plastic barrels for daily food, plastic pots and bottles are mostly made of polyethylene or polypropylene, of which polyethylene is more common. Polyvinyl chloride can also be made into barrels, pots, etc., but like the film, it cannot hold food, especially oil and wine. There are also aldehyde plastics commonly known as "electric jade" and melamine formaldehyde plastics commonly known as "melamine", which contain formaldehyde in the raw materials. In the production process, if the polymerization is not good, free formaldehyde may appear in the tableware. Formaldehyde is a very toxic substance, such as mixed into food, will seriously damage human health. Therefore, it is necessary to use good quality "electric jade" and "melamine" tableware and utensils.
Recycling and packaging manufacturers recommend that the relevant departments should strictly control the inferior products and prevent them from coming out. Although polyethylene containers can be used to hold food, they should also be used to load oil. Since polyethylene is soluble in oil, if it is stored for a long time, the color and taste of the cooking oil will change, even if it is not edible, which will damage health.www.fhpails.com
