Matters needing attention in advance processing

Precautions for the advance processing of aluminum hoses for cosmetic hoses'>Precautions for the advance processing of aluminum hoses for cosmetics hoses. As a common packaging material, aluminum hoses are not only because they have relatively high airtightness, oxidation resistance and Corrosion resistance, and it can effectively block oxygen, odor, sunlight, ultraviolet rays, and most importantly, non-toxic and odorless. Therefore, it is widely used in cosmetic packaging, pharmaceutical packaging, chemical ointment packaging, etc., for filling hand cream, Hair dye, glue, ointment, paint, etc. After the aluminum hose is stamped and formed, there are multiple processing steps such as inner spraying, primer, printing, tailing glue, tail sealing, and top cover. But not all packaging aluminum The pipes need to pass through all the processes. Which processing process should be used for aluminum hoses is selected by the characteristics of the filling content and the needs of product planning.

Let's deepen our understanding of aluminum hose processing procedures based on some daily problems.
1. Which products require internal spraying for aluminum hoses? Answer: Products that are highly corrosive, flexible and easy to change, and easily react with metals, such as strong acid glue. Because the material selected for internal spraying is mainly epoxy phenolic resin, which can prevent corrosion, oxidation, and fall;
2. Which products of aluminum tubes need primer? Answer: The first choice of primer is plump polyester resin, which forms a protective film on the surface of the aluminum tube to avoid oxidation and corrosion of the aluminum material. Aluminum tube packaging for cosmetics, hair dye cream, etc., plus primer, can make the printing effect better;
3. Which products of packaging aluminum tubes need to be printed? Answer: The printing mainly includes offset printing, silk printing, etc., which are mainly selected according to the planning needs of the product. Packaging of cosmetics, paints, etc., in order to be more beautiful, will be printed to attract more customers;
4. Which products of aluminum tubes require tail glue? Answer: The main function of the tail glue is to enhance the sealability after sealing, avoid leakage of the paste, block the contact of the contents with air and moisture, and ensure the shelf life of the paste. Therefore, it is a product that is more watery and easy to leak. For example: glass glue, cosmetics, need to add tail glue;
5. Which packaging aluminum tubes need double-folding? Answer: Those quick-drying glass glue and AB glue. Double-layer sealing makes better sealing performance. Although aluminum hose processing medical hose is not a high-tech process, but to manufacture high-quality packaging aluminum tubes, every process must be paid attention to. After all, the finished product is perfect. Presented in front of customers.
