Classification Of Environmentally Friendly Materials For Disposable Tableware

Classification Of Environmentally Friendly Materials For Disposable Tableware

The following is a summary of the current mainstream environmentally friendly materials and their characteristics:

1, Plant fibers
Sugarcane bagasse/sugarcane fiber
The raw material is the waste residue from sugarcane pressing, achieving the recycling of agricultural waste;
Water resistant, oil resistant, microwave resistant, recyclable or naturally degradable after use.
Bamboo fiber
Made from bamboo as raw material through dehydration and hot pressing processes;
Combining environmental friendliness and practicality, it has high hardness and is waterproof and oil resistant, with a wide temperature range (-50 ℃ to 280 ℃).
Corn stalks/reed pulp
Made from discarded crop straw, with low cost and complete biodegradability.

2, Starch based materials
Starch degradable round bowl
Using starch such as corn and potatoes as raw materials, molded into shape through natural polymer materials;
It can be decomposed into harmless substances by microorganisms, and the degradation time is affected by environmental factors such as temperature and humidity.

3, Paper materials
Pure wood pulp paper/bamboo fiber paper
The raw materials are sourced from natural wood or bamboo, and there are no chemical additives in the production process;
Can quickly and naturally degrade, but has weak waterproof properties, suitable for cold or light food packaging23.

4, Biobased polymer
PLA (Polylactic Acid)
Made from bio based materials such as corn and sugarcane, it has good heat resistance;
Tableware is made through high-temperature injection molding process, with low carbon emissions and complete degradability.

5, Fully degradable composite materials
Made by mixing various environmentally friendly materials (such as plant fibers and starch), it has both strength and degradation performance;
The degradation products are harmless to the environment and have passed international safety certification 35.

6, Light/biodegradable plastics
As photobiodegradable PP materials, they gradually decompose under light or microbial action;
Suitable for scenarios that require short-term durability, the environmental friendliness is significantly improved by 28 compared to traditional plastics.
