Digital printing is quietly squeezing traditional printing, you know

If digital printing technology without printing plates started from the first copier made by American Chester Carlson in 1938 using electrostatic imaging principle, then digital printing was widely accepted by the world and became a new round of market hot spots after the Druba Printing Exhibition in 2016. Because, Heidelberg, Komori and other traditional printing equipment manufacturers almost all enter this field, which means that they are optimistic about the next development of digital printing. In fact, in recent years, the application of digital printing in various fields has also risen and fallen. The most fundamental reason is that the market is changing. For example, the earliest application of variable data printing

Packaging material structure suitable for microwave

According to the principle of microwave, combined with the heat resistance of packaging materials, the structure level of plastic flexible packaging materials adapted to microwave should be scientifically selected. Ordinary plastic composite flexible packaging materials are only suitable for microwave heating and microwave thawing; for microwave cooking, microwave drying, microwave sterilization and other lack of use safety; ordinary plastic flexible packaging materials should be prohibited for microwave baking and microwave puffing, and special appliances must be used. 1. Single-layer structure regular plastic films include: PET, OPP, PE, CPP, NY, EVOH and other flexible packaging materials single-layer film, can be used as food packaging materials, microwave heating, microwave can directly pass through these materials, energy evenly into the packaging of food. 2, plastic structure Plastic-plastic structure flexible packaging composite films are the most common, mainly including multilayer films compounded, such as: PET // PE, NY // PE, PET // CPP, NY // CPP, OPP // PE, OPP // CPP, PET // NY // CPP, OPP // PVDC // CPP, etc. Composite films made by multilayer co-extrusion process are as follows: PE/PVDC/PE, PE/EVOH/PE, PE/NY/PVDC/NY/PE, etc. These composite membranes can also be passed through by microwaves without substantial loss of microwave energy. 3. Paper-plastic structure Paper/PE, wax/paper/PE, PE paper/PE, etc., the paper-plastic structure can also be passed through by microwaves, but the passing efficiency of the paper-plastic structure is affected by the moisture content in the paper. The higher the moisture content of the paper, the greater the loss of microwave energy. The loss of energy causes the temperature of the packaging material to rise, and the heating efficiency of the packaged food will be slightly affected. It should be noted that: because metal reflects microwave, single-layer aluminum foil and aluminum-plated film, and composite film containing aluminum foil and aluminum-plated film can not be used for microwave heating.

Table and inside printing of plastic packaging

Most of the products on the market are packaged with plastic films. Most of them need to display product information on the surface. Here, printing is needed on the film. Plastic packaging has single-layer and composite films. Their corresponding products are single-layer surface printing and composite inner layer printing. For plastic film substrates, these two kinds of printing are used in gravure printing, so what is the difference between them?

The unique printing effect of the outer packaging-partial matte

Plastic film material has the advantages of light weight, transparency, moisture resistance, oxidation resistance, acid resistance, alkali resistance, good air tightness, easy to print exquisite graphics, etc., and is widely used in the packaging of convenience foods, daily necessities, and supermarket commodities. After printing compound or bag making processing, it is made into a bag shape and the contents are sealed. The dazzling array of goods on the shelf has its own unique outer packaging, and many food companies like to achieve a partial matte effect on the outer packaging, thereby enhancing the product quality. So how is this effect printed and what points should be paid attention?
