1、Material combination: PLA + NKME + PBS
Insulation layer: NKME, the insulation of NKME is at the top level among biodegradable materials, which can well guarantee the taste of coffee beans.
Printing layer: transparent PBS. Due to the excellent properties of PBS, it can be waterproof and 9-color printing as a printing layer.
2、Material combination: PLA + Kraft Paper
Inner layer: PLA with high cost performance and good thermoplasticity is used as the heat sealing layer, which is 100% degradable.
Outer layer: The insulation is slightly inferior to NKME, and it also has a very good protective effect on the taste of coffee
beans. At the same time, your design can also be directly printed on kraft paper, which can complete 5-color printing.
3、Material combination: PLA + NKME + Kraft Paper
Inner layer: Milky white PLA
Outer layer: NKME and kraft paper together form the insulating layer. The best isolation effect, as a coffee bag, can protect the taste of coffee beans to the greatest extent. Kraft paper as the outermost layer can achieve up to 4-color printing.
