Packaging aluminum-plastic tube:
The tube of this material is used to hold various ointment tubes, such as toothpaste tubes, cosmetic cream tubes, glues, lubrication tubes, pigment tubes, etc., but due to the difference in the paste So what specifications and parameters should be paid attention to when choosing cosmetic aluminum-plastic tubes?
First of all, the aluminum-plastic tube is used as the packaging material to be filled. The first thing to pay attention to is the existing filling machinery and equipment. What are the specifications of the aluminum-plastic tube that can be adapted? If the equipment conditions cannot be adjusted, the size of the aluminum-plastic tube that can be adapted to the machine should be selected to ensure smooth filling and production.
2.The proportion of contents
The specific gravity of the paste content is different, and the applicable aluminum-plastic tube size is also different. The same two products with a capacity of 5ml, the product with a higher specific gravity will have a larger total weight.
Different sizes of packaging aluminum-plastic tubes have their corresponding capacity ranges, which are usually estimated in units of ml. You can confirm whether they reach the desired capacity or weight through trial filling.
