- The process of making polypropylene roll sheets by an extruder machine
- Polypropylene roll sheet printing process by thermoforming machine and vacuum machine
- Cup printing process by printing machine. The production of trays and lids does not go to the printing process, including plain cup variant products according to buyers' requests.
Polypropylene roll sheet is a plastic sheet that has been rolled to a specified thickness and width with natural, white, brown and other colors as needed.
Polypropylene sheet rolls have an average diameter of 100 cm according to the height of the unwinder in the thermoforming machine or vacuum machine.
The raw materials for making polypropylene roll sheets are:
- Polypropylene regrind
- Recycled plastic crusher results
- Supporting polypropylene regrind for example color polypropylene regrind, thickening propylene regrind, cold-resistant polypropylene regrind and semi-finished polypropylene regrind such as RK or RG..
- PP He2.0TF
- Bi 5.0Ga-P
- PP Elpro 400S
- PP Hy38Fy
- PP Hy3.8Fy Near Prime (OG)
- PP Petrovietnam NSY114G
- PP Moplen Hl400H
- PP Polimaxx S1003
- PP Cosmoplene AW161
- PP Yuhwa Polypro 5014
- PP Masplene MAG2160
- PP Trilene Hl10HO OG (Off Grade)
- PP Masplene MAG 2158
- PP Masplene MAG3352
- PP Trilene Bi 50Ga
- PP Trilene Bi 50GN
- PP Masplene MAS3355
- PP Yarn Titanpro 6531
- PP Petrovietnam BSR 3034T
- PP 510SCP400H
- PP Masplene MAS2158
Furthermore, one of the most important things to get a polypropylene roll sheet that meets quality standards is to regulate the composition of the raw materials mentioned above.
The following is an example of setting the material composition for a polypropylene roll sheet:
- 100% natural propylene regrind to produce high quality natural color polypropylene roll sheets.
- 50% natural polypropylene regrind and 50% natural polypropylene plastic recycling crusher results to produce second quality natural propylene roll sheets
- 40% natural polypropylene regrind, 10% natural class 2 polypropylene regrind and 50% natural Polyptopelene plastic recycling crusher results for third quality natural polypropylene roll sheets.
If the desired product needs to be tougher then the material composition can be added with LLDPE regrind (not polypropylene material) as much as 10% of the polypropylene regrind.
If the desired product must be cold-resistant, for example for ice cream containers that are stored in the freezer, cold-resistant regrind can be added with a composition of 50% of the total polypropylene regrind.
If the desired product has a certain color, for example white, then all materials must be white (white polypropylene regrind, white recycled plastic crusher) and the addition of white master bacht is around 2% of the total regrind.
