What plastics can be used in pharmaceutical packaging?
HDPE (high density polyethylene), bearing cleaning supplies, plastic containers, bath products currently used in supermarkets and shopping malls in the plastic bag is made of such material, resistant to high temperature of 110 DEG C.PE is the most widely used plastic in industry and life. It is usually divided into two kinds: high-density polyethylene (HDPE) and low-density polyethylene (LDPE). PE is good for acid and alkaline resistance. HDPE has higher melting point and hardness than LDPE, and is more corrosive to corrosive liquids. At present, the plastic bags and translucent or opaque plastic bottles are almost all made by PE, such as detergent, shampoo, bath milk, edible oil and pesticide... And so on, most of them are dressed in HDPE bottles. General transparency.
PS (polystyrene), good transparency, low water absorption, PS is mainly used in building materials, toys, stationery and so on, can also be made of common container filling dairy fermentation (such as Yakult, health fitness, and so a lot of dairy products or products such as lactic acid), in recent years also made extensive use in disposable tableware.
PP (polypropylene), microwave oven boxes made of this material, resistant to 130 degrees high temperature, poor transparency, this is the only plastic box can be put into the microwave oven, after careful cleaning can be repeated use.
PET (polyethylene terephthalate) was originally used as artificial fibres, films, tapes, etc., and was only used in beverage bottles in 1976. Using PET as a raw material for filling a container, is commonly known as the "bottle". Excellent hardness and toughness of plastic bottles, light weight (only the weight of glass bottles of 1/9 ~ 1/15), convenient to carry and use less energy consumption, production, and airtight, non-volatile, acid and alkali, is a carbonated beverage pack material. In recent years become carbonated drinks, tea, fruit juice, bottled water, wine and soy sauce and other products of filled containers, in addition, packaging bottles such as cleaning agent, shampoo, food oil, spices, sweet food, medicines, cosmetics, and alcoholic beverages, have been widely used in plastic bottles.
