What are the plastic lids usually made of? Besides, what are the materials made of them?
For example: PP bottle bottle PE, such as ink cans, bottles of mineral water bottles, such as PET, PVC such as lotion bottles, cosmetic bottles, cosmetics bottles of PMMA AS PC five gallon bucket PS medicine bottle and so on, too many varieties of plastic. No write.The lid is the same reason, the daily use of PP, PE mostly.
This problem is too large, you have the best set of industry, regardless of whether the lid or bottle, you can use a variety of plastic, the key is to look at product requirements. You said you need to understand the industry, I can add answers.
