Cardboard packaging is needed primarily for, to keep the goods in safe and sound. packing, the main purpose of which is precisely the safety of goods during transport and storage, commonly referred to as production. There are other types of carton packages, which performs several other tasks, eg, contains advertising or explanatory information, attracts the buyer and goes to him along with the goods. They are called consumer. Let's take a closer look at the differences between both types, as well as, how is it going production of cardboard packaging.
For storage and transportation
Made using low quality recycled paper. Has great strength. Used for product packaging, building materials, equipment, because there is a wide range of not only auto, furniture and other similar goods. Turnover color – brown or gray.
For consumers
When creating such packaging, high-quality cellulose paper is used.. Such packaging is endowed with less strength., but will attract the appearance. It usually has a smooth surface., on which information and artistic printing are applied. Is used for:
- perfumery,
- medicines,
- cosmetics,
- some products, eg, tea, confectionery and others.
Consumer packaging has a white turnover color.
Production of cardboard packaging
The first type of packaging is often made from corrugated board.. They have a long service life, shock and vibration resistance, and also have a low cost. The production process of corrugated board packaging will be discussed below.. To create it indoors, certain conditions must be met.: high humidity around 80% and air temperature around 20 degrees. Raw materials for the production of corrugated cardboard are supplied in the form of rollers..
The resulting raw material must be unwound on a special machine. Then the cylinders with temperature 160 degrees warm paper. This contributes to better gluing and folding of future packaging..
At the next stage, the paper enters the corrugating press, due to which characteristic waves are obtained on it. This layer will serve as a shock absorber for greater safety of goods..
After that, the corrugated layer must be connected with a flat. To do this, a layer of corrugated paper is smeared with glue., based on corn starch, with good environmental and bonding properties. Layers compress each other. At this stage, after drying, two-layer corrugated cardboard will be ready.
For greater strength and better appearance, a third layer can be added.. In this case, corrugated cardboard is placed between two layers of flat cardboard.. Three-layer corrugated cardboard is more rigid, than two-layer, so it is folded ready, not twist.
To get a box, corrugated cardboard is cut to the desired dimensions with the addition of valves, which are very useful when folding. PVA glue is used in the right place. In this way, the well-known cardboard box for packaging is obtained., transportation and storage of goods.
