However, when a person stands on top of Kraft paper45g/PLA+PBAT50 compostable foil pouch for 10~15 seconds, it will not burst.	Bruce 2024-11-22	0865	Bruce 2024-11-22 12:12
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.	Bruce 2024-11-22	0824	Bruce 2024-11-22 12:11
So Kraft paper/BOPLA pouch can only be intended for light-weight products package, like 5~100g.	Bruce 2024-11-22	0850	Bruce 2024-11-22 12:11
When working as inner sealing layer, BOPLA film is much fragile than PLA+PBAT film.	Bruce 2024-11-22	0799	Bruce 2024-11-22 12:11
However, in most cases, the standing effect of Kraft paper/PLA+PBAT pouch will be great for most of the products.	Bruce 2024-11-22	0801	Bruce 2024-11-22 12:11
With better stiffness, actually Kraft paper/BOPLA pouch will present better standing effect than Kraft paper/PLA+PBAT pouch.	Bruce 2024-11-22	0903	Bruce 2024-11-22 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.	Bruce 2024-11-22	0855	Bruce 2024-11-22 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.	Bruce 2024-11-22	0831	Bruce 2024-11-22 12:10
Therefore, the final blown PLA+PBAT film should not be considered as full plant-based film materials.	Bruce 2024-11-22	0624	Bruce 2024-11-22 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	Bruce 2024-11-22	0844	Bruce 2024-11-22 12:09
Anyway, BOPLA film can be taken as full plant-based film materials.	Bruce 2024-11-22	0807	Bruce 2024-11-22 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.	Bruce 2024-11-22	0799	Bruce 2024-11-22 12:09
PLA is a thermoplastic monomer derived from renewable, organic sources such as usually derived from cassava, corn-startch or sugarcane.	Bruce 2024-11-22	0685	Bruce 2024-11-22 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	Bruce 2024-11-22	0710	Bruce 2024-11-22 12:08
Check this video below for a further understanding.	Bruce 2024-11-22	0707	Bruce 2024-11-22 12:08
It is semi-transparent, with coffee beans filled in, and people can see the blur image of the products.	Bruce 2024-11-22	0838	Bruce 2024-11-22 12:08
This picture shows the unprinted compostable standup doypack with foil materials kraft paper 45gsm/PLA+PBAT60 microns.	Bruce 2024-11-22	0796	Bruce 2024-11-22 12:08
The below vidow shows a further profile for this compostable standing doypack.	Bruce 2024-11-22	0792	Bruce 2024-11-22 12:07
You can check the below graphic for further understanding.	Bruce 2024-11-22	0747	Bruce 2024-11-22 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.	Bruce 2024-11-22	0825	Bruce 2024-11-22 12:07
