Three different kinds of materials usually make out for rice bags
Material 1: nylon composite film. This kind of rice packaging bag is a high-grade packaging bag. It can vacuum package rice in 2.5KG, 5KG, 10KG and other specifications. It can be color printed and can be equipped with handles. One of the most popular materials for rice vacuum packaging bags is available on the market. The material characteristics are as follows:
The nylon composite film is characterized in that: from top to bottom, there are nylon layer, polyethylene layer and nylon layer in turn, an adhesive layer for adhesion is sandwiched between the upper nylon layer and polyethylene layer, and an adhesive layer for adhesion is sandwiched between the polyethylene layer and the lower nylon layer. The nylon composite membrane has a simple structure. Because the middle layer is polyethylene layer and the upper and lower layers are nylon layers, it can withstand high temperature and has a wider application range.
Material 2: plastic woven bag, which is custom-made and printed with 10KG, 15KG, 20KG and other large rice packaging bags. The material characteristics are as follows:
The material woven bag is mainly composed of polypropylene bag and polyethylene bag; According to the sewing method, it can be divided into bottom sewing bag and edge sewing bag. At present, it is widely used as a packaging material for fertilizer, chemical products and other articles. The main production process is to use plastic raw materials to extrude film, cut, stretch unidirectionally into flat wires, and then weave them through warp and weft to obtain products, which are generally called woven bags.
Material 3: Kraft paper plastic bag. Customized packaging bags of this material are mainly 2.5KG and 5KG. Kraft paper plastic rice packaging bags can be customized in small quantities, with a minimum order quantity of thousands, so it can effectively reduce the packaging cost of rice merchants, but the printing effect and the grade of rice packaging bags are no less than composite rice vacuum bags. The material properties are as follows:
Kraft paper plastic composite bags are mostly made of kraft paper and plastic products. They are usually made of some polyethylene materials and polypropylene materials, while kraft paper is made of some fine composite kraft paper. The two are bonded by melting plastic hot laminating film. Kraft paper coated cloth is formed by bag making, and then processed and sewn into a three in one paper plastic bag for packaging and plastic sealing. Features: It has high strength and good waterproof performance, and the appearance of the product is also very beautiful. Self sealing strip can be added to make the entire product packaging bag stand up. The combination of kraft paper and plastic film makes the product packaging almost perfect!
