Three composting solutions, different combinations have different barrier properties:

• solutions1: 2 layer, High Barrier+Dual Coated+Degradation of aluminum plating

•  solutions1: 3 layer, High Barrier+Dual Coated+Degradation of aluminum plating+Kraft Paper

•  solutions1: 3 layer, Medium Barrier,+Dual Coated+Kraft Paper

Please tell me the following information before quoting:

• Are there any printing requirements?
• Tell me the transparency you need，Semi-transparent or highly transparent, usually the price of high transparency will be higher
• Are there any specific requirements for the barrier properties of bags?

If you have,please tell me the acceptable water permeability and oxygen permeability values.

• What do you use the bag to pack?

Our compost packaging raw materials include the following types:

• Highly transparent three-layer co-extruded PLA film, thickness: 20-100u, can be used for window opening and single-layer bag making. The transparency and feel are very similar to BOPP, and the flatness is very good.
• Semi-transparent film, a transparent film made from a unique blend of cornstarch and PBAT, a bio-based polymer. Thickness: 20-100u, can be used for window opening and single-layer bag making.
• Kraft paper
• Home composting low temperature heat sealing PBS film
• Double-stretched PLA biodegradable thin aluminum film: thickness is 15u, water permeability is 10-20, heat sealing strength is 5-10N
• PLA biodegradable high-barrier thick aluminumfilm: thickness is 20-80u, water permeability is 2-4, oxygen permeability: 1.5-2, heat sealing strength is greater than or equal to 30N, and the feel is softer. Great for coffee bags and pet food bags.
• PHA
• Degradable zipper: Semi-transparent easy-tear zipper
• Degradation exhaust valve
