Which coffee packaging materials are sustainable development packaging?

For example, the leaders of the international coffee industry such as Nestlé have changed the coffee capsule from the original injection molding multi-layer material to a single material of aluminum forming, and actively advocated consumer classification to actively recycle. Products sold in my country can also be recovered by consumers in the form of waste recycling to achieve a good social value cycle by centralized recycling. From cowhide to low-density polyethylene (LDPE), recyclable and reusable materials in coffee packaging have been widely used for many years. However, not all materials are equally easy to recover. However the extra functions, such as degassing valve and additional layers can greatly change our way of processing coffee packaging.

The popular recyclable coffee and food packaging in the baking plant is LDPE single material soft packaging. LDPE is a thin, light and flexible thermoplastic plastic that can withstand temperatures above 100 ° C. It is composed of two layers of LDPE films. The outer layer prints and coats to achieve matte/light, touch, and other functions. PE single -material recyclable plastic food packaging can block water, oxygen and precipitated carbon dioxide that making it very effective in maintaining the freshness of coffee. The deficiency is that PE material cannot achieve the shading of traditional aluminum foil composite packaging (the EU PE recycling standard determines that black PE cannot be used as recyclable PE) which it is not easy to achieve the appearance of PE single -material packaging is quite width, flatness, transparency, and tearing resistance than traditional composite packaging.
