What materials are available for packaging cartons
With the development of the global packaging industry and logistics industry, the quality of packaging cartons is becoming more and more demanding, especially after long-distance transportation of packaging boxes, there is a decline in the printing effect caused by the warping of corrugated cardboard, moisture absorption resulting in softness, sizing resulting in product damage and scrap, returns, claims and other events, it is clear that the quality of packaging cartons is important to the packaging and logistics industry, so, together with the following to understand what materials are available in packaging cartons!
Corrugated boxes are commonly used with three layers, five layers, seven layers with less usage, each layer is divided into lining paper, corrugated paper, core paper, lining paper. The lining paper has tea paperboard and kraft paper, and the core paper uses corrugated paperboard. The color and touch of each type of paper is different, and manufacturers make different paper (color, touch). The following is a summary of the various raw paper materials used in corrugated packaging cartons Introduction.
1, tea board paper: tea board paper is gray in color and rough, a kind of tea board paper mixed with old materials, with little fiber content and average quality. Tea board paper is the paper in the middle of the corrugated carton layer and is soft. Because the quality is not good, so the price of tea board paperboard is also cheap.
2, corrugated boxes.
1) tea board paper: tea board paper color grayish white, characteristics: long fiber, heavy size, high physical strength, corrugated paper coarse; wood pulp or a small amount of OCC. Abbreviation: imported kraft card.
2) Imitation kraft cardboard. Features: surface hanging 15-25% wood pulp, the rest is OCC; short fibers, strength is worse than kraft paper. Paper surface flat, size (water absorption of different 30-55g/m2), surface dyeing treatment. Abbreviation: domestic kraft card.
3) White cardboard. White-faced kraft card base, surface bleached wood pulp, the rest is natural or dyed wood pulp, (off-white, Swedish white, Finnish white); white board paper (surface bleached wood pulp, the rest is deinked or non-deinked waste paper)
4) Recycled paper. All composed of OCC, but different from corrugated board. The surface is treated with 11# or more of AOCC hanging dye, and the market is generally known as Class C boxboard, partly known as uncle paper.
3, corrugated paperboard raw paper: corrugated paper is a multi-layer bonded body, rarely composed of waveform core paper sandwich and corrugated paper. It has high mechanical strength and can withstand collisions and falls in handling. Corrugated paper corrugated is like a connected arch, arranged and supported by each other, forming a triangular structure body, with good mechanical strength, able to withstand a certain pressure on the plane, elastic, good buffering, and can be made into various shapes and sizes of gaskets and containers as needed, easier and faster than plastic buffering materials; small temperature impact, shading The effect of temperature is small, light blocking is good, and it does not deteriorate when exposed to light, and the effect of humidity is small in general, but it is not suitable for long-term use in high humidity environment, which will affect the strength.
Corrugated packaging cartons have become one of the most demanded product packaging forms in recent years because of its strong content protection, easy identification, easy to carry, easy to open, beautiful printing and other characteristics.
