The use of cosmetics bottles with good performance

Medicinal plastic manufacturers to carry on the good control in the production and design, according to certain production and processing technology for production and production, and has good performance and function, can fully show important value in the industry. 1) When designing extrusion type of medicinal plastic bottles, if is made of high density polyethylene or polypropylene, plastic bottles of cross section should be rectangular or oval, low density polyethylene or other flexible material for plastic bottle, its round cross section as well. Such facilitating contents from out from the plastic bottles. Used with plastic bottle of the plastic parts are mainly cover and seal. The design of plastic bottle should focus on; About how to make the plastic bottle can better cooperate with cover and seal the bottom of the plastic bottles, plastic bottles is weak parts of the mechanical properties. Therefore, medical plastic bottle at the bottom of the general design into inner concave; Plastic bottles of the corner, and inner sunken place, all do larger arc excessive. For convenience of plastic bottles stacked, increasing the stacking stability of plastic bottles, plastic bottles should be designed at the bottom of the groove. 2) The surfaces of the medicinal plastic bottles labeling, should be so that the cover is flat and level. In the surface of the plastic bottle design a 'box', make the labeling accurate positioning, do not produce movement. In blow molding, the parison swell touching part first, always tends to hardening of the first part.
