At present, China's rice vacuum packaging bags mainly use plastic woven bags and composite plastic bags as packaging containers, and some problems in transportation, loading and unloading, retail and other aspects of these vacuum packaging bags have been solved. Using plastic woven bags to package rice, the waste will be more serious, generally only used 1-2 times, the relative cost is also high. It is difficult to seal the package after it is simply opened, which is not conducive to long-term preservation. The phenomenon of pests and mildew in woven bag packaging is also serious. The moisture-proof and barrier of packaging materials are poor, and the grain is easy to be oxidized and mildew.
Plastic composite bags are made of high barrier packaging materials. To a certain extent, they solve the problem of Rice's mildew prevention, insect prevention and preservation, but the post-treatment is relatively difficult. This kind of packaging materials are not easy to degrade, which is not conducive to the current concept of environmental protection, and its development is limited to a certain extent.
At present, there are basically two kinds of packaging forms in the market, one is ordinary packaging, which uses polypropylene plastic woven bags to package rice without any fresh-keeping technology in the packaging process. This kind of packaging has poor effect on insect and mildew prevention of rice. The other is to use vacuum packaging technology to vacuumize the vacuum packaging bag. The vacuum technology has a better fresh-keeping effect on the storage of rice, but it is not suitable for the selection of the shape and vacuum degree of rice itself. At present, the vacuum degree of rice vacuum packaging is generally between - 0.07 and - 0.09kpa. As long as the vacuum degree is within the range, all the products are qualified.
The fresh-keeping packaging of rice should be combined with the circulation environment at the same time, so as to ensure the better quality and protection of rice products. Our company produces high quality products with exquisite technology, which is deeply trusted by our customers. Welcome to our company, we will serve you wholeheartedly.
