What are home biodegradable Kraft coffee pouches made of?

2023-10-31

home biodegradable Kraft Coffee Pouches are typically made from a combination of materials to ensure that they are suitable for storing and preserving coffee. These materials often include:

Kraft Paper:

Composition: Kraft paper is made from wood pulp, usually obtained from softwood trees like pine, spruce, or fir. The pulp is processed in a way that retains long fibers, giving Kraft paper its strength and durability.
Biodegradability: Kraft paper is naturally biodegradable. When it is discarded and exposed to environmental conditions, it can decompose relatively quickly, as it is primarily composed of organic matter. Microorganisms and natural processes break down the paper over time, returning it to its basic components.

Biodegradable Laminates:

Composition: Biodegradable laminates or coatings are used on the inner layer of the coffee pouch to provide a moisture barrier and protect the coffee from external elements. These laminates are typically made from biodegradable materials, with one common choice being Polylactic Acid (PLA).
PLA (Polylactic Acid): PLA is a biopolymer made from fermented plant starch, usually derived from sources like corn or sugarcane. It is a biodegradable and compostable material.
Biodegradability: PLA and similar biodegradable polymers will break down naturally in the environment, typically under the right conditions of heat, moisture, and microorganisms. They can be composted, returning to organic matter without causing long-term harm to the environment.

Biodegradable Adhesives:

Composition: Biodegradable adhesives are used to bond the various layers of the pouch together. These adhesives are specially formulated to break down naturally over time.
Types of Biodegradable Adhesives: There are several types of biodegradable adhesives, which may include starch-based adhesives, water-based adhesives, or adhesives derived from natural sources like algae or seaweed.
Biodegradability: These adhesives are designed to degrade and become part of the natural environment over time. They are chosen for their ability to break down without leaving persistent residues.

Resealable Zipper or Valve:

Our coffee pouches come equipped with a resealable zipper to allow for easy opening and closing, which helps keep the coffee fresh after the initial use. Our pouches also feature one-way degassing valves to release gases produced by freshly roasted coffee while preventing outside air from getting in.

1. Compostable Resealable Zipper:

Material: Our companies offer compostable resealable zippers made from materials like compostable bioplastics or paper-based materials. These zippers are designed to break down in a home composting environment.
Functionality: They provide the same convenience as traditional resealable zippers but with the added benefit of being eco-friendly.
Disposal: After use, consumers can remove the compostable zipper from the pouch and place it in a compost bin. Over time, it will decompose, reducing the environmental impact.

2. Biodegradable One-Way Degassing Valve:

Material: Our manufacturers are exploring biodegradable materials for one-way degassing valves. These materials can include biodegradable plastics or even edible materials.
Functionality: These valves still allow for the release of gases produced by freshly roasted coffee while preventing the entry of oxygen.
Biodegradation: While these valves may not break down as quickly as Our compostable materials, they are designed to biodegrade over time, reducing their environmental impact.
