The application of PCTG in cosmetics packaging materials

One, understand PCTG

PCTG is a kind of transparent plastic, is a kind of amorphous type copolyester, PCTG commonly used for copolymerization monomer 1, 4 - Cyclohexane two methanol ( CHDM) , called the polyethylene terephthalate - 1, 4 - Cyclohexane 2 methyl ester. It is made of terephthalic acid ( PTA) And glycol ( 如) And 1, 4 - Cyclohexane two methanol ( CHDM) The product of three kinds of monomers by ester exchange method of polycondensation, for more than 1, 4 - compared with PET Cyclohexane two methanol copolymerization monomer, and PCT more than glycol monomer, therefore, PCTG and performance of PET, PCT. PCTG is a noncrystalline copolymer polyester, with the increase of CHDM in the copolymer, drop melting point, glass transition temperature rise, crystallinity decreased, the final formation of amorphous polymers. General PCTG CHDM content at 30% 40% more appropriate.

has good viscosity, transparency, color, resistant to chemicals, and the ability to resist stress whitening. Can quickly heat molding or extrusion blow molding. Viscosity ratio of acrylic ( Acrylic) Good. Copolyesters PCTG is a kind of amorphous type, its products are highly transparent, excellent impact resistance, especially suitable for thick wall molding transparent products, processing and shaping its excellent performance and can be carried out in accordance with the intention of the designers of any shape design, can use the traditional extrusion, injection molding, blow molding, blister, molding method, can be widely applied in the plate sheet, high-performance shrinkable film, bottles and special-shaped material, cosmetics manufacturer packaging market, at the same time, the second time processing performance is good, can undertake conventional machining.

2, PCTG applications in cosmetics manufacturer packaging industry

PCTG has the transparency of glass and close to the glass density, good gloss, resistance to chemical corrosion, impact resistance, and easy processing, injection molding, injection blow molding and extrusion blow molding. Also can produce the unique shape, appearance, and special effects, such as bright color, frosted glass, marble texture, metallic luster, and so on. But also can use other polyester, elastic plastic overlapping or ABS plastic injection molding.

products are perfume bottles and caps, cosmetics bottles and caps, lipstick tubes, cosmetic box, deodorant bottle packaging, talcum powder and eyeliner pen cap, etc. PETG plastic injection products are medical devices such as filters, eustachian tube, pipe fittings, pump, clip and dialysis equipment. Household items such as glass containers, salad bowl, salt, pepper cans, excellent transparency and gloss, good toughness, processability and excellent pigmentation.

PCTG is a kind of high transparent copolymer polyester plastic raw materials. With high transparency, good toughness and impact strength, excellent low temperature toughness, tear resistance and good processability, excellent chemical resistance. Can take the traditional extrusion, injection molding, blow molding, blister forming methods for processing, etc. Widely used in the plate sheet, high-performance shrinkable film, bottles and special-shaped material market; Can be used in the production of toys, household items and medical supplies, etc. ; Passed the American FDA standards on food contact, can be used in food, pharmaceutical, cosmetic packaging and other fields.
