Ordinary paper bags also have an oil-proof effect, but some greaseproof papers are hard, and some are soft. Is the hard greaseproof paper better in quality, or the softer one?
Experts pointed out that if the greaseproof paper has good hardness, it is easy for people to carry. Everyone thinks that the quality is better. This kind of thinking is also reasonable, but specifically:
1. The thickness of the greaseproof paper is determined by the thickness of the film before the greaseproof paper is laminated. Products with a thickness within an appropriate range are regular products.
2. The hardness of greaseproof paper is very different, we only need the right one. First of all, the thickness of the product should be determined according to the thickness before lamination, and the thickness of the product after lamination should be controlled within an appropriate range. In addition, there is a one-to-one correspondence between barrier and thickness, and the size of the barrier has a corresponding effect. Although greaseproof paper with good barrier properties is hard, it is not necessarily thin, but the consistency of thickness and barrier properties is Not great, as long as they're embalmed in average conditions.
3. For the same package of wrapping paper, the thicker the thickness, the higher the temperature on the paper bag. Experts point out that ordinary greaseproof paper has standard thickness and thinness. The main purpose of this kind of paper bag is to have an anti-corrosion effect. The better the anti-corrosion property, the better the quality. The difference is still huge, but the thicker the greaseproof paper, the higher the cost. On the other hand, it is also inconvenient for everyone to use and carry, and also produces a certain amount of waste of resources.
4. Compared with other greaseproof papers, good greaseproof papers have more standard and refined printed graphics and characters.
