Deng karaniwan a gagamitan a thermal machine kayabe la plastic cup machines, PLC Pressure Thermoforming Machine, Hydraulic Servo Plastic Cup Thermoforming Machine, etc. Nanu la reng plastic a gamitan da? Oreni reng mapilan a karaniwan a gagamitan a plastic a materyales.
mga 7 klasing plastic
A. Polyesters o PET
Deng polyesters o PET (Polyethylene terephthalate) metung lang malino, matibe, matatag a polymer a maki pambihirang gas ampo moisture barrier properties. Maralas magagamit ya para mika carbon dioxide (alias carbonation) kareng butul a soft drinks. Kayabe la kareng kayang aplikasyun deng film, sheet, fiber, tray, display, imalan, ampo wire insulation.
B. CPET
Ing CPET (Crystallized Polyethylene Terephthalate) sheet gawa ya keng PET resin na me-crystallize para dagdagan ing kayang temperature tolerance. Ing CPET maki katangian ya keng matas a temperature resistance, keraklan pilatan ning -40 ~ 200 °C, metung yang masanting a materyales para keng pamaglalang ovenable plastic food trays, lunch boxes, containers. Advantages ning CPET: malyari yang i-recycle keng gilid ning dalan at malyari yang ilub keng recycle bin kaybat nang mehugas; Ligtas yang gamitan keng microwave ampo keng freezer; at deng lulanan a pamangan a reni malyari lang gamitan pasibayu.
C. Vinyl o PVC
Ing vinyl o PVC (Polyvinyl chloride) metung ya kareng peka karaniwan a materyales a thermoplastic. Atin yang kalupa a katangian ing PET a magpakit masanting a kalinawan, e makatusok, at makadikit. Keraklan gagawan de kareng sheets a kaybat mabuu lang dakal a produktu. Bilang metung a pelikula, ing vinyl makahinga yang ustu a dagul inya sa't masanting ya para keng pamagbalut kareng sariwang karni.
D. PP
Ing PP (polypropylene) atin yang maragul a high-temperature chemical resistance at magagamit ya keng pamaglalang packaging cup, fruit tray ampo food container.
E.PS
PS (polystyrene) ing pekamaragul a thermoforming material 20 banua na ing milabas. Atin yang masanting a processability ampo masanting a dimensional stability pero limitadu ya ing solvent resistance. Deng gamit na ngeni kayabe la reng pamangan ampo medical packaging, housewares, toys, furniture, advertising displays, ampo refrigerator liner.
F.BOPS
Ing BOPS (Biaxially oriented polystyrene) metung yang komersyal a materyales a pang-packaging, na atin yang bentahe ning biocompatibility, e makalasun, transparency, light-weight ampo cost-effective. Metung ya namang bayung materyales a e makasira keng kapaligiran keng pamagbalut pamangan.
