How to distinguish PET bottles?
PET containers are usually formed at the bottom or side, with a triangular "chase arrow" symbol around the number 1 and the abbreviation PET or PETE below the triangle.
Only PET carries an identification number 1.
Factors affecting the gift paper box
So when it comes to carton gift paper boxes, there is no doubt that these boxes are made from cartons, in fact, people who know about cartons know that the reasonable collocation of cartons is to ensure the carton compressive strength of the basic conditions. But speaking of this, there should be a lot of people are not so understanding of this aspect, so since the mention of the carton type gift paper box production, so now we will tell you about the carton gift paper box production, what factors will be affected by it. The production process of cartons will also affect the compressive strength. According to the test, under the same conditions, the compressive strength of the carton decreases by 90n ~ 130n and the deformation of the carton increases by about 2mm for every 1mm widening of the transverse pressure line of the carton. Pressing line too wide, will cause the carton in the compression test force increase slowly, effective value is small, large deformation. In order to...
