Developed a convenient paper vapor bag abroad

Foreign countries have developed convenient paper food bags that do not use steamers and microwave ovens to heat foods. The bags of paper can only pass through steam. Therefore, the packaged foods can be easily reheated by immersing them in boiling water, so that meat, fish, etc. Cook evenly. The length of the single fiber of the newly developed steam bag is longer than that of plain paper, and will not break even if it is immersed in water for a long time. Its processing method is mainly to use additives in the pulp to achieve its special purpose. This kind of paper bag adapts to people's requirements for diversification of heated food packaging, brings convenience to people's lives and has a good play space.
