Biodegradable Plastic
a) Melt PBAT compounding with PLA or PPC
The melt PBAT material with temperature 240℃ is fed into twin screw extruder by a melt pump, and add the PLA or PPC pellets and chain extender additive into extruder by the loss-in-weight feeder. This is direct compounding which can save 40% energy and better dispersion, comparing with PBAT pellet compounding with PLA or PPC
◆ Needs long L/D for reacting
◆ Needs under water pelletizing system for high output capacity and automatically process
◆ Needs vacuum packing system
b) PLA/PBS compounding with starch powder
◆ Premix and long L/D for better dispersion
◆ Special feeder for anti-bridge
◆ Air cooling die face cutting for PLA base, and air cooling strand pelletizing for PBS base
◆ Need vacuum packing system
c) PVA compounding with starch
◆ Two stage mixer for premixing and reacting
◆ Special feeder for anti-bridge
◆ Air cooling die face cutting system, need water cooling jacket for die plate
◆ Need vacuum packing system
Colour Masterbatch
1.Three types of Color Masterbatch
1) Mono color masterbatch or SPC (single pigment concentrate): polymer compounding with one single pigment and mostly without the wax and additive.
2) Tailor-Made masterbatch or Custom coloring: mixing different Mono color masterbatch pellets to get the color the customer wants.
3) Customized masterbatch: mix polymer and several pigment and additives.
2.Base Resins: PE/PP/PS/PVC, PET/PA/PBT, TPE/TPR/EVA…
Pigments: Organic pigments, Inorganic pigments incl such asTiO2, carbon black…
Additives: PE wax, Anti oxidant, ZnSt
Application
1) Fiber ( Carpet, Textiles, Upholstery, etc . )
2) Film ( Shopping bags, casting film, multiple layer film, etc . )
3) Blow Molding ( Medical & Cosmetic container, Lubricant & Paint container, etc . )
4) Extrusion Molding ( Sheet, Pipe, Wire & Cable, etc . )
5) Injection Molding ( Automotive, Electronic, Construction, House wares, Furniture, Toys, etc . )
PET, PLA/PBAT, and PP sheet
plastic extrusion machine, PET, PLA/PBAT, and PP sheet products can be produced by the same machine. Used for different applications, for example, PET sheet is environment-friendly material, and is widely used in our daily life, food packaging, cups, cup lids, electric packaging, polyester fibres, furniture decorative product, medicine treatment, agricultural seeding trays, etc. PLA, biodegradable material can be used in rigid packages of vegetables, fruit, eggs and baked goods, cups, food trays, etc. PP, sheet has single layer sheet and multi-layer sheet, widely used for thermoforming products, food packages and electrical component package. PP transparent thermoforming sheet can be used for plastic cup, food tray, etc.
