First, the history of plastic bottles:
80 years of the 20th century, as China continued from abroad advanced production line of plastic bottles, opened with "plastic" on behalf of the "glass" the prelude, from plastic bottles to be used widely in packaging. Plastic bottles which are mainly non-toxic polymers such as high density polyethylene (HDPE), polyester (PET), polypropylene (PP), polycarbonate (PC) as the main raw material, the use of advanced plastic molding process and equipment for production of plastic bottles, mainly dressed all kinds of capsules, tablets, powders, granules, capsules, oral liquid, solid and liquid, etc..
Second, the use of plastic bottles:
Domestic market to sell drugs, dietary supplements, all food and drinks most of the use of plastic bottles, you casually stroll to the drugstore or supermarket, you can see the products packaged in plastic bottles. Medicines and nutritional healthcare products mainly used to polyester bottles (PET bottles) and high density polyethylene bottles (HDPE bottles), the major use of PET beverage bottles (PET), daily necessities such as shampoo, shower gel, use high-density polyethylene bottles (HDPE bottles) more. Plastic bottle features the largest light weight, unbreakable, clean, beautiful, and its large number of technical indicators and data show that its chemical resistance, excellent water vapor permeability of seals, which can be loaded entirely within the period of product safety shielding and protection products play a role.
Third, the principle of selection of plastic bottles:
l, no matter what material do choose plastic bottles, first of all must be consistent with non-toxic, no smell, etc., as the main raw materials for a wide variety of choice, which need to be selected combination of properties of raw materials, tablets usually use high-density polyethylene ethylene, polypropylene bottles, such as the need for transparency can be used PET bottles (PET bottles), if necessary, higher barrier properties, and stop light, opaque, brown PET bottles are used, the liquid formulations of drugs generally used in the polypropylene bottles or PET bottles as the main raw material. Currently the nutritional health products and food packaging PET bottles are mainly used for making fertilizer or HPDE, cap is PP material with
2, bottle and cap sealing, water vapor permeability. Sealing and water vapor permeability of plastic bottles are two important technical indicators, they play the packaged products of crucial importance for the stability of the impact.
3, plastic bottles product quality standards. From the production plant quality standards of product quality can be analyzed to judge the merits.
4, the quality assurance system. Audit of the supplier purchase plastic bottles has become the essential part. Through the audit, can plant the software and hardware facilities, technical equipment, comprehensive level of quality to make a comprehensive assessment of the right.
5, used for packaging drugs, dietary supplements, food and beverages must not use recycled materials issued by the Ministry of Health, "Plastic products and raw materials, food hygiene management measures," which clearly provides: "Where the processing of plastic utensils, containers, food packaging material, shall not use recycled plastic. "regulations is November 26, 1990 promulgated the.
4, plastic bottles status
Life everywhere plastic bottles, plastic bottles and is closely related to people's daily life, is none, I do not know something well-known everywhere in the. China also has a large base of plastic recycling, but the regulation does not regulate, good and bad times missing reference. In addition to a lot of plastic bottles made from recycled materials, production on people's health physical harm, there is pollution in the work en route, but also seriously endanger the health of consumers.
Ministry of Health, "Plastic products and raw materials, food hygiene management measures," which clearly provides: "Where the processing of plastic utensils, containers, food packaging materials, shall not use recycled plastic." Recycling of waste plastics can be processed into other products. Many businesses now driven by the interests, tend to choose low-cost recovery of materials to manufacture products, it is indeed worrying. If you are using course there are impurities found in the bottle, transparent bottle of transparency is low, we should alert, and polish your eyes,
