Do you know what are the common paper packaging materials in life?

As we all know, paper is a recyclable resource. Papermaking raw materials are mainly plant fiber, raw materials in addition to containing cellulose, hemicellulose, lignin three main components, there are other less content of components, such as resin, ash and so on.

Product packaging is an important part of the product, it not only plays a protective role in the transportation process, but also directly related to the comprehensive quality of the product. Commodity packaging, usually made of paper or cardboard, is called paper packaging. The following are our commonly used paper packaging materials.

01, honeycomb paper

The inner core of honeycomb paper is a lot of closed holes, because its internal air is not circulated, so it has good thermal insulation, thermal insulation, sound insulation performance. At the same time, only after some special treatment, honeycomb paper can be flame retardant, moisture-proof, mildew proof. Honeycomb paper is widely used, not only can be used as a packaging material in various products, but also can use honeycomb paper instead of conventional building materials as a partition wall, which can effectively reduce the weight of the building. Honeycomb paper can also replace wood to make furniture, not only durable, but also can save wood.

02, corrugated paper

The corrugated paper bonded by the corrugated paper and corrugated roller processing is generally divided into two categories: single corrugated board and double corrugated board, which has the advantages of low cost, light weight, easy processing, high strength, convenient storage and handling.

03, kraft paper

Kraft paper main features: Kraft paper is tough water resistant packaging paper, brown-yellow color, a wide range of uses, often used to make paper bags, envelopes, workbooks, record sleeves, rolls and sandpaper, the quantitative range is 80 grams/square meter to 10 grams/square meter, there are web paper and flat paper, and there are single-sided light, double-sided light and striped differences, the main quality requirements are flexible and strong, high break resistance, Can withstand large tension and pressure without rupture. Kraft paper has a high tensile force, single light, double light, stripes, no lines and so on.

04, single powder paper/double powder paper

Single powder paper: commonly used carton materials, such as: coated paper, matte powder paper, etc., one side of the paper is light, one side is dumb, smooth surface can be printed, and various colors can be printed, commonly used surface treatment processes are: over-glue, over-UV, hot printing, bumping and so on.

Double powder paper: Double powder paper is gray cardboard, usually thicker. More than 250 grams, used for mounting paper, mounting pit, mainly for large outer packaging.

05, paper bag paper

Paper bags are similar to kraft paper, mostly produced by coniferous wood sulfate pulp, but also mixed with some bamboo pulp, cotton stalk pulp, rag pulp production, so the mechanical strength of paper bags is very high, generally used to make cement, pesticides, fertilizers and other industrial packaging bags. In order to meet the requirements of filling, the paper bag paper requires a certain degree of permeability and greater elongation

06, special paper

Special paper refers to paper with special uses and relatively small output. A wide variety of special paper, is a variety of special purpose paper or art paper collectively. Special paper is the use of different fibers to make paper with special functions, such as the use of synthetic fibers alone, synthetic pulp or mixed wood pulp and other raw materials, with different materials to modify or process, give paper different functions and uses.
