The weight of the paper is closely related

For companies making disposable paper bowls made by paper bowl machines to make sense of it, it is important to do a good job of printing, focusing on printing design and improving aesthetics. Choose rich colors for the printing design and use more attractive patterns that will attract the attention of consumers. In the choice of materials, choose good quality materials. When carrying out the design, pay attention to grasp the psychology of consumers and pursue diversity to attract more consumers and expand sales.

The weight of the paper

There are usually two ways of expressing this, one is quantitative and the other is called order weight.

Quantitative is the weight of the paper per unit area, expressed in grams per square meter, and it is the basic basis for paper measurement. The minimum quantitative paper is 25 grams per square meter and the maximum is 250 grams per square meter. Quantification is divided into absolute dry quantification and air-dry quantification. The former refers to the completely dry, moisture equal to zero states of quantitative, the latter refers to a certain humidity to reach moisture balance when the quantitative. The latter refers to the latter. The quantification is carried out under standard temperature and humidity conditions (1 degree above or below 23 degrees; 2% above or below 50 relative humidity).

500 identical sheets of paper are called a decimal, and the weight of a decimal is called the decimal weight of that type of paper. Internationally there are also 480 or 1,000 sheets for one order, and special attention needs to be paid to this when dealing with foreign paper business and using imported paper.

Order weight is commonly used in the printing industry, and what we mean by weight is the specified amount, i.e. the number of grams per square meter of paper. Weight is a very important parameter of paper, in technical terms, weight is the basic condition for various performance appraisals (e.g. strength, opacity); in everyday applications, weight is often used to classify paper bowls made by paper bowl machines into grades, which, of course, does not mean that the heavier the paper bowl made by paper bowl machine is, the better it must be.

A4 paper = 210mm x 297mm, area = 0.06237m2, the general specification for A4 paper is 70g/m2 or 80g/m2, and the weight of an ordinary A4 paper is 4.3659 grams or 4.9869 grams.

Do you know what kind of instant noodle bowls you use every day?

The common material used for instant noodle bowls made by paper bowl machines is polyethylene (PE) laminated paper-plastic composite products, which are regulated for heavy metals and fluorescent substances and clearly state that "recycled raw materials should not be used". Instant noodle bowls generally have six layers, from the inside to the outside: the first layer is food-grade polyethylene plastic film, cling film is also often polyethylene, to comply with GB 9687-1988 "food packaging with polyethylene molding products health standards", the applicable temperature is below 100 degrees, can be waterproof, but the too high temperature may be some of the additives leachings. The second layer is the inner layer of paper, which is food-grade white paper and must comply with GB 11680-1989 "Hygienic Standard for Raw Paper for Food Packaging". The third layer is the outer layer of paper, also known as grey cardboard, mainly to improve the hardness of the paper bowl made by the paper bowl machine; the fourth layer is the printing paper, name, trademark, and other information; the fifth layer is the varnish, a transparent coating, appearing bright, both to protect the role of the ink layer; the outermost layer is generally the packaging film, to protect the product packaging.
