The thickness of the plastic bags really so important?
In daily life, people often use the plastic bag, but little attention to the thickness of the plastic bags.Understanding of the thickness of the plastic bags also only stay in, plastic bags are quite thick, not easy to break.
The thickness of the plastic bags is also decides the plastic bags which aspects?
1, products first depends on the thickness and thickness uniformity of the thickness of the plastic bags before the compound single-layer film and uniformity, that is to say, good control the thickness of the plastic bags monolayer film quality is to get qualified product thickness quality conditions.
2, bag film barrier property is closely related to the thickness of the plastic bags film (usually is proportional to the thickness of contact), evenness good bag film can obtain uniform in secure barrier property.
3, bag film thickness uniformity directly affects the mechanical drawing function of thin film, thickness uniformity, good bag film can achieve good printing overprint precision and quality of composite.
4, as the compound bag membrane lining material, thickness on the high side began to heat sealing temperature is high, and vice versa.That is to say, the thickness of composite bag membrane can be obtained from the sealing quality, uniform prevent part of the heat sealing is undesirable.
5, customers are mostly according to square meters as delivery data, can be useful to manipulate composite film processing cost.
