From:www.jweicut.com View:1330 times

From design to packaging material selection to printing, cutting, gluing, etc., a lot of professional knowledge is involved in this lengthy process. Take packaging materials for example. You may have heard of them but are unfamiliar with them. What materials are suitable for where? What are the characteristics? As a packaging cutting expert, JWEI will introduce several very commonly used materials today:

  1. White card, also known as single powder

This is a very commonly used carton material on the market. The thickness of the paper varies from 80g to 400g. The surface and bottom layers are white. It is smooth on the one side and rough on the other side. Single-layer or multi-layer paper;

  1. Double powder, also known as coated paper

Coated paper is a very common material. The two sides are white and the two sides are smooth. It is a kind of base paper with white pigments, adhesives, and other auxiliary materials, which are evenly coated on the plate-coating machine and made by drying and super calendering.

  1. Pit paper

Pit paper is a piece of smooth kraft paper and wavy paper (collectively called paper core) laminated, is one of the important materials for paper packaging. Compared with ordinary paper, it is more straight and has a stronger load-bearing capacity. Commonly used are single pit, double pit, and three pits, which can realize printing in various colors, but the effect is not as good as single powder.


  1. Cardboard

Cardboard is also called cardboard. A thick paper sheet made of various pulps and interwoven with fibers. Commonly used for making gift box structures, with a layer of single-powder paper or special paper on the surface.

  1. EVA

EVA: The full name of Ethylene Vinyl Acetate Copolymer is made of ethylene and acetic acid copolymer, which has the characteristics of strong toughness, impact resistance, shock resistance and anti-skid. It is often used in packaging and interior to fix and protect the surface of products. It can also be used in flocking and fleece cloth processes to enhance visual effects.

  1. Sponge

It is a porous material with good water absorption and elasticity. It is often used in packaging and inside to fix and protect products. Generally, no superposition process is required, and it can be used directly.

For the materials commonly used in the above packaging, in the subsequent processing, all the latitude and longitude can be cut and fixed. Through the warp and weft packaging cutting solution, you can easily solve the problem of post-packaging processing and undertake personalized customized orders with high profits and large added value. It has been widely used in corrugated packaging plants, color box packaging plants, proofing studios, knife mold factories, etc. The digital proofing equipment provided by the solutions of the JWEI packaging industry abandons the traditional knife-die proofing process, saving labor, materials, time and other costs.
