A large number of paper bag packaging has also brought a large development space to the market.
Let's analyze the paper raw materials used in the production of several shopping bag portable paper bag machinery :
The thickness of the common paper bag machine raw materials is 120g-300g natural kraft paper. Kraft paper is generally suitable for printing single-color or double-color and uncomplicated color manuscripts. Compared with white cardboard, white kraft paper box coated paper, yellow kraft paper has the lowest price.
Kraft paper bag packaging raw materials are widely used in shopping bag paper bag machines because they have good physical properties and adaptability. The paper bags made are relatively hard and have a better texture than other paper bags. They are suitable for placing some valuables, such as jewelry, watches, etc. Kraft paper is used as raw material to produce various types of paper bags: including handbags, cement bags, laminated paper bags, four-layer paper bags, clothing bags, food bags, shopping bags, gift bags, etc.
Paper weight range: Kraft paper (yellow kraft leather, white kraft leather): 80-300g;
Kraft paper is mostly produced from softwood sulfate pulp. Domestically, some bamboo pulp, cotton stalk pulp, and rag pulp are also used to produce paper bags. Therefore, the mechanical strength of paper bags is very high, with high tensile strength, tear strength, rupture work and dynamic strength. It is tough and inexpensive, with good folding resistance and water resistance. Most of them are roll paper, and there are also flat paper. It can be divided into single light, double light, striped, unpatterned, etc., with white and yellowish brown colors. It is generally used to make packaging bags for industrial products, mainly used for packaging paper, envelopes, shopping bags, food packaging paper bags, etc. It requires a certain degree of air permeability and a large elongation (stretching paper).
Kraft paper is often used to make shopping bags due to its durability and environmental protection characteristics; white cardboard is suitable for paper bag machines to produce high-end shopping bags due to its high strength and beautiful printing effect; kraft paper bags are tough and water-resistant packaging paper, which are environmentally friendly materials and are often used to make paper bags, envelopes, files, exercise books, etc. The quantitative range is 80g/㎡ to 10g/㎡. Paper bags can be reused and are pollution-free. Due to the advantages of kraft paper, it decomposes much faster than plastic, so it has more environmental protection functions.
