PLA+PBAT film, is a blown film from the mixes of PLA and PBAT resion certificated by ASTM 6400 standard to be compostable materials. PLA is short for poly-actic acid, which is a thermoplastic monomer derived from renewable, organic sources such as corn starch or sugar cane. PBAT is short for polybutylene adipate terephthalateis , which is biodegradable random copolymer. This film works as inner sealing layer for this final biodegradable package, with great sealing strength and final fine protection for the products.

Artwork Printing

A good creative artwork matters much more than most people expect, as most people tend to buy a product they feel good for.

For the printing produce in our plant, we are able to achieve the artwork in maximum 10 colors. With in-line print defect inspection system, more than 98% of the common print defects can be removed, you may have a further understanding by below video.

We will have to request a minimum order quantity of 10,000 bags against customer artwork. As to print each color, there will be a tank of printing inks offered to the rolling print cylinder. If we print only 5, 000 pcs, that will be huge waste of inks, film materials and labor.

So if the customer is just looking for hundreds or thousands of coffee bag, he is advised to take from the stock items, like matte white coffee bag or matte black coffee bag, that should be much more cost-effective than custom printed bag.
