paper packaging request

It is understood that this new type of paper package has a 1.5-fold increase in strength compared to ordinary paper bags. The packaging bag has a reasonable and firm structure. For example, the paste bottom bag adopts a trapezoidal arrangement, and each layer is independently bonded to make it more firm. A bag of four-story stretch paper bags full of 25 kilograms of flour is free to fall 10 times at a height of 1.2 meters. The paper itself has hygroscopicity, can absorb excess moisture in the food, and can effectively prevent the food from getting damp due to the damp environment. At the same time, the tightness of the paper bag is better than the cloth bag. Under the same conditions, the shelf life can be extended by two to three months. 

In order to reduce the loss of grain during storage, transportation and sales, China's grain packaging has undergone continuous upgrading, from sacks, woven bags to composite plastic bags, and is stronger than generation one.

The prominent advantages of the paper bag are non-toxic, odorless, non-polluting, and in line with national food hygiene standards. Because the printing performance of the paper is good, the graphic characters can be printed according to the user's request. The valve paper bag made of this paper is very convenient and rapid in the filling process of the flour, the filling speed can be increased by 3 times, and there is no dust flying, and the working environment can be improved.
In addition, since the paper bag is rectangular after filling, it is easy to palletize and is not suitable for sliding. The same amount of storage can increase the storage capacity by 10%. The handling process does not contaminate the clothes of the operators. In view of the above advantages, people in the industry believe that the promotion of the use of paper grain packaging is inevitable in the future replacement of grain packaging, and is also the development trend of grain packaging in the future.
With the improvement of people’s living standards, new consumption concepts and consumption structures have put forward higher requirements for food commodity packaging. People need high-quality rice noodles, and they need to be easily purchased and easily carried. However, traditional grain sales packaging and transportation packaging are almost indiscriminate, and there is no special packaging for retail links. The use of whole-bag purchases and stacked sales methods for sale is neither convenient nor hygienic. Therefore, there is a need for hygienic, sturdy, convenient, and aesthetically pleasing packaging in order to adapt to changing market demands.
Insiders pointed out that small food packaging must have the following properties:
1) The safety protection of food quality, which involves shielding, protection, stability, and hygienic safety;
2) Machinability, involving processability, printability, heat sealability, etc.;
3) Easy to use, light weight, easy to carry, store, open, and open, the mark is obviously easy to purchase;
4) Economic performance, ie, ease of production, rationality, energy saving;
5) Environmental performance, namely, recyclability and degradability.
According to the above requirements, among the various existing packaging materials, the industry generally favors paper packaging. For example, in rice paper packaging in Heilongjiang, 0.5kg-1kg paper bags are used as small packages, and 10 small packages are loaded into corrugated cartons as outer packaging. This package is very hygienic and reliable, economical and practical, easy to use and conducive to environmental protection.
Experts believe that multi-layer paper bags are used as small food packaging, and their domestic research has only just begun. For example, the weight, size, shape of bags, shape of bags, requirements for different grain products, climate change, shelf sales and different shelf life, storage and transportation methods, and surfaces. Decoration, printing, and the establishment of standards for the unified inspection of multi-layer paper bags and the degree of automation of their packaging machines must be further studied. But no matter what, grain paper bag packaging will be more and more widely used.
