As you can check the pressure test in the below video, when we strikes on the kraft paper/BOPLA pouch, it is much easier to burst. New	Bruce 昨天 12:11	03	Bruce 昨天 12:11
So Kraft paper/BOPLA pouch can only be intended for light-weight products package, like 5~100g. New	Bruce 昨天 12:11	02	Bruce 昨天 12:11
When working as inner sealing layer, BOPLA film is much fragile than PLA+PBAT film. New	Bruce 昨天 12:11	02	Bruce 昨天 12:11
However, in most cases, the standing effect of Kraft paper/PLA+PBAT pouch will be great for most of the products. New	Bruce 昨天 12:11	03	Bruce 昨天 12:11
With better stiffness, actually Kraft paper/BOPLA pouch will present better standing effect than Kraft paper/PLA+PBAT pouch. New	Bruce 昨天 12:10	03	Bruce 昨天 12:10
BOPLA film presents much better mechanical property after orientation, and the stiffness increases so much, and then laminated with kraft paper, the final foil laminate will be much better stiffness than kraft paper/PLA+PBAT foil. New	Bruce 昨天 12:10	03	Bruce 昨天 12:10
So Kraft Paper/BOPLA foil pouch can be taken as full plant-based materials pouch, however Kraft Paper/PLA+PBAT foil pouch is not the one. New	Bruce 昨天 12:10	03	Bruce 昨天 12:10
Therefore, the final blown PLA+PBAT film should not be considered as full plant-based film materials. New	Bruce 昨天 12:10	03	Bruce 昨天 12:10
However, PLA+PBAT film is actually a blown film from the mixes of PLA and PBAT resin. PBAT, short for Polybutylene Adipate Terephthalate, is a new type of biodegradable and compostable plastic which is derived from fossil chemicals New	Bruce 昨天 12:09	02	Bruce 昨天 12:09
Anyway, BOPLA film can be taken as full plant-based film materials. New	Bruce 昨天 12:09	02	Bruce 昨天 12:09
Machine direction orientation (short as MDO) and transverse direction orientation (short as TDO) can be achieved on the orintentation zone of the produce line after the film is cased onto the chilling roller. New	Bruce 昨天 12:09	03	Bruce 昨天 12:09
PLA is a thermoplastic monomer derived from renewable, organic sources such as usually derived from cassava, corn-startch or sugarcane. New	Bruce 昨天 12:09	03	Bruce 昨天 12:09
Kraft Paper/BOPLA film can be considered as fully plant-based materials packages, as actually BOPLA (short of biaxial orientated polylactic acide) film is made of pure poly-lactic acide New	Bruce 昨天 12:08	03	Bruce 昨天 12:08
Check this video below for a further understanding. New	Bruce 昨天 12:08	01	Bruce 昨天 12:08
It is semi-transparent, with coffee beans filled in, and people can see the blur image of the products. New	Bruce 昨天 12:08	02	Bruce 昨天 12:08
This picture shows the unprinted compostable standup doypack with foil materials kraft paper 45gsm/PLA+PBAT60 microns. New	Bruce 昨天 12:08	02	Bruce 昨天 12:08
The below vidow shows a further profile for this compostable standing doypack. New	Bruce 昨天 12:07	02	Bruce 昨天 12:07
You can check the below graphic for further understanding. New	Bruce 昨天 12:07	02	Bruce 昨天 12:07
This above picture shows the comostable standup pouch with foil laminate kraft paper 45gsm/BOPLA40micron, with texts printed on the surface of kraft paper. New	Bruce 昨天 12:07	01	Bruce 昨天 12:07
PBS film is of much higher price which cause a big trouble for its commercial application New	Bruce 昨天 12:07	01	Bruce 昨天 12:07
