Coffee and milk tea have a good market, disposable paper cups and lids have made great contributions for it. Most of the customers like to use PLA paper cups, because PLA paper is waterproof, and it can maintain cups dry, safe and harmless. The advantages of PLA paper cups will be shown in the following.


1. PLA paper cups have water resistance, good air permeability. This cup has high surface strength and interlaminar strength, because the penetration rate is higher than other materials. PLA paper cups are antibacterial, and can absorb ammonia.


2. This disposable paper cup belongs to food paper, and it has advantages of mildew proof, water absorption and water resistance. The wrapping film is made through a special process with protein as coating on the paper, which can withstand a certain temperature, prevent erosion, be convenient for food processing, and do no pollution to the environment.


3. Polylactic acid (PLA) is a new bio-based and renewable biodegradable material, which is made from the starch extracted from renewable plant resources (such as corn, cassava, etc.). The starch is saccharized to get glucose, which is then fermented through a certain kind of bacteria to produce high purity lactic acid, and then the lactic acid is synthesized to get polylactic acid. PLA disposable paper cup has good biodegradability and can be completely degraded to carbon dioxide and water by microorganisms in nature under specific conditions, causing no pollution to the environment.


PLA paper cups use natural renewable plant resources as raw materials, which reduces the dependence on the traditional oil resources and accords with the requirement of sustainable development of the international society. It has both the advantages of synthetic fiber and natural fiber, and features in completely natural circulation and biological decomposition. Compared with the conventional fiber, corn fiber has many unique properties, making it preferred and valued by customers.
