A brief analysis of the development history of packaging paper
Nowadays, among the four pillar packaging materials of paper, plastic, metal and glass, Tianjin paper products are developing extremely rapidly. Its price is extremely inexpensive and it can be recycled and keeps the green environment. Now the development of paper packaging materials in our country has a few following points.
Research and development of food packaging paper functional type special cardboard, paper bags with logo
At PRESENT in our COUNTRY, THE WHITEBOARD is of a single variety, NOT CLASSIFIED FOR packaging DIFFERENT THING, AND NOT dedicated FOOD PACKAGING BOARD for DIFFERENT FOOD NEEDS TO PRODUCE. Although THE raw material and the HEALTH INDEX are regulated for the FOOD PACKAGING PAPER IN OUR COUNTRY, THERE is NOT THE kind OF BOARD SPECIALLY USED FOR FOOD PACKAGING, A variety OF FOOD BOX USED grey bottOMING WHITEBOARD. As the packaging board of direct entry food, such as pastry boxes and quick food boxes, is not oil-resistant, it is fairly common for oily food to be soaked. In the future, special functional cardboard should be developed and produced for packaging different kinds of food, such as carton cardboard for packaging pastries and other foods that can be directly imported, can cardboard for packaging semi-finished foods that are steamed, roasted and processed, and can cardboard for packaging milk and fruit juice.
Develop natural green packaging materials
Natural plant fibers (straw, wheat straw, cotton straw, bran, etc.) can be used as quick food boxes, but also can be rolled or woven to make convenient bags. Some natural plant fibers are tall and strong, easy to weave into grass bags. Bamboo, natural shrubs, wicker, etc., can also be woven into baskets, baskets and other packaging containers or made into natural bamboo tubes for holding fruits, vegetables, tea, etc. Bamboo plywood packing boxes can be used for machinery, electrical equipment and other transportation packaging. Natural mineral materials such as clay, ceramics can be made into wine, tea and additional packaging. The rock particles expanded into lighter perlite, adding a slight adhesive, can be made into different shapes of buffer packaging.
Develop vegetable fiber snack boxes
With the enhancement of people's awareness of environmental protection and the practical needs of life, disposable paper fast food boxes and other food packaging products are popular. However, the cost of paper quick food boxes is steep, so it is extremely necessary to develop quick food boxes using rice straw, wheat straw, bagasse, bran and additional crop fibers as raw materials. This kind of product is competitive in price. It can nourish fertile soil after use and degradation, and can also be used as livestock feed when collected. The resources are adequately utilized and it has excellent economic and social benefits.
Numerous packaging materials, is the rapid development of paper products, from the quality and price are the first choice. We have learned some about the development trend of paper products, summarized for you to share with reference.
Packing paper, board and box board paper high quality lightweight
In order to make full use of natural resources and reduce mailing and transportation costs as much as possible, it is the developing trend of paper products all over the world to produce a variety of paper, board and carton boards with low quantity. The problem of low quantity has been put forward in newspapers, relief printing paper and offset printing paper, and the problem has been solved. Packaging paper and cardboard products should also achieve high-quality lightweight and variety diversification. Especially for the corrugated base paper and kraft board paper, according to the domestic market's large demand for superior-quality packaging boxes, three low-quantity products should be added on the premise of properly improving the quality of the original products, namely, a different variety of 100g/m2 for corrugated base paper and two varieties of 21g/m2 and 200g/m2 for kraft board.
To develop straw pulp-based disposable tableware special board
Its main technical characteristics are:
(1) Based on the raw materials resources in our country and aiming at the shortcomings of raw materials for grass pulp, the application technology of chemical additives improving the quality of grass pulp is adopted to ensure that its properties are close to the physical properties of wood pulp.
(2) Processing suitable for food packaging is carried out on the surface of the cardboard, so that the finished cardboard has the functions of hot water resistance, no leakage, no stratification, oil resistance and heat sealing. The economical and reasonable method is to use raw bleached straw pulp to produce paper tableware, and then recycle waste tableware to produce non-food packaging paper, so as to make full use of fiber resources without polluting the environment and increasing the pulping load.
