Cosmetics bottles should have several characteristics

Cosmetics bottle manufacturers explain for everybody in the production of a qualified health care products plastic bottles should have the following characteristics: the penetration: mainly is to prevent the volatile substances between molecules spread out from the vessel wall. In particular, some paper and PE single plastic film packaging, such as obvious breathe freely, pervious to light, through the performance of the water, not only drug aromatic ingredients from the wall to escape and can directly through the cosmetic bottles, such as gas and water vapor into the container, and affect the stability of health food. In order to prevent the penetration phenomenon, when choosing packaging materials should choose permeability small individual packaging materials for medicines. This aspect of composite membrane containers, glass containers, metal containers, ceramic container effect is better. Shading: efficacy ingredients such as vitamin E in illumination is the oxidation, such as coating pills, tablets ( Especially citric yellow color clothes) Because light makes a dark, so that to effectiveness. For this kind of health food packaging, also need to shading in addition to the seal. Health food packaging shading often USES three measures: (1) traditional use brown paper parcel all inside cosmetics bottle or bottle; (2) new material system with aluminum alloy membrane, aluminum, paper-plastic composite film; (3) in adding sunscreen cosmetics bottles, such as titanium dioxide. Containment: health food volatile or not volatile components, the solid or the liquid drug through discontinuous or packaging materials, such as the material on the pinhole, cracks or gap between cap and cosmetics bottles and escape or leakage. This kind of situation mostly occur in the structure of cosmetics bottles under the condition of improper design and packaging technology, of course, sometimes caused by improper material. Thermosetting cosmetics bottle is refers to the heat or other conditions can be cured or insoluble ( Melt) Properties of plastic, such as phenolics, epoxy plastic, etc. Thermosetting plastic and formaldehyde crosslinking points type and other crosslinking type two kinds. After molding, hot working form not melt insoluble content, curing the resin molecular couplet net structure of a linear structure. To strengthen the heat will decompose. Typical thermosetting plastic with phenolic resin, epoxy, amino, unsaturated polyester, furan, the material such as silicon ether, and the new eps 2 formic acid 2 acrylic ester plastic etc. They have the advantages of high heat resistance, heat distortion. Defect is generally is not high mechanical strength, but by adding fillers, made into laminated material or moulding material to improve its mechanical strength.
