Key points of cosmetic tube quality inspection

Nowadays, the quality of cosmetic packaging has become the second life of cosmetic products, and brand owners are paying more and more attention to packaging quality.

Plastic tubes are widely used in cosmetic cream products and beauty salon products because they are light in weight, easy to carry, strong and durable, recyclable, good resilience, easy to squeeze and process, easy to print, and good adaptability. Aluminum-plastic composite tubes, all-plastic composite tubes, and plastic co-extruded tubes are the most commonly used.

So, how do people judge whether the quality of this packaging material tube that directly contacts the contents and skin is in line with people's health and hygiene needs, and meets people's expectations? How to judge what kind of packaging material tube supplier can meet people's requirements?

For service stability, suppliers must first dare to take responsibility. Guangzhou Lisson Plastic Co., Ltd. (Lisson for short, LISSON in English) has been committed to providing long-term stable high-quality products and caring services, so that customers have no worries.

The stability of the product, brand purchasers may know that poor adhesion of the color block and ink drop of the color block may occur when the tube is printed with large color blocks. Lisson has deliberately taken steps to strengthen the product stability in response to these phenomena. In the production of large color block products, the workshop will be required to do adhesion test after adjusting the machine, and formally produce after the test is qualified.

In addition, Lisson's method in the production process of offset printing is to increase electrophoresis to improve adhesion, while in the silk screen printing process, conditions such as increasing the temperature of the UV lamp and prolonging the lamp illumination time are used to ensure the stability of the adhesion. Therefore, the stability of Lisson's products is that it has a good reputation and reputation in the industry.

In addition to the raw material particles of plastic tubes, they must comply with relevant laws and regulations, such as FDA, SGS certification, and the production process and environment must also ensure the hygiene and safety characteristics of cosmetics.

Lisson has always put tube hygiene as the focus of quality control. Lisson has specially produced a device for handling dust before inspection (commonly known as a two-way vacuuming nest). It uses a high-power suction port in both the horizontal and upper and lower directions to allow each When a product passes through the suction port, the free dust and dust that may exist in the tube surface and the tube will be automatically sucked away. Of course, the cleanliness of each product will be repeatedly checked and processed to ensure the hygiene and safety of the product.

Good protection is the most basic requirement for packaging materials. It should have sufficient mechanical strength, a certain degree of barrier properties, chemical resistance, weather resistance, and also the airtightness of plastic products to protect them from damage during transportation. Measures and so on.

The so-called sufficient mechanical strength means that the product tube packaging can have compression resistance, impact resistance, and bending strength. For plastic tubes, it also requires good resilience to ensure that it can return to its original shape after being squeezed. ; And chemical resistance is shown in oil resistance, grease resistance and acid resistance, etc.; weather resistance is shown in temperature resistance, dimensional stability, environmental stress cracking resistance, etc.-these characteristics are the basis of Lisson tube, nearly 99.9 %do the best!

In addition, for packaging containers such as tube products, Lisson has carried out a comprehensive and strict sealing test from the beginning of the mold inspection. The product is filled with water for 12 hours without leakage. During the production process of each batch of products, Lisson will conduct a comprehensive and strict sealing test. Leakage test, every time a defective product is found, the entire batch of products will be considered as unqualified-therefore, under such high requirements and standards, to ensure that the protection of the product reaches the highest value, for so many years, Lisson's products have been It is to win the praise of customers.

How to protect it during transportation? If the tube has a large face bronzing design, or equipped with electroplating caps, equipped with acrylic caps, Lisson will recommend the way of separate plastic pouches for each product to avoid scratches during transportation; and for locking cap products, Lisson will adopt locks The way of lid and boxing makes it convenient and efficient for customers to take the tube when filling; for line-sealing products, Lisson will box the lid with an outer diameter of 30mm or more, and use white paper between each layer to achieve the product. It is easy to access while protecting.

Products that have been approved by the market must maintain fast-reading identification, which is also conducive to after-sales recycling and disposal.

Therefore, Lisson will read the barcode designed by the customer and check the correctness of the reading. From the product design draft to the actual product, Lisson will use the scanner to test, and any defects will be reported and resolved immediately.

Lisson will conduct a first test during the proofing process, and use a special barcode scanner to detect it. When the product is officially mass-produced, it must be read and tested before the first product is confirmed and completed to ensure that the product is qualified. To an important safeguard role.

Lisson has a complete quality control system, from material input to manufacturing process to packaging. Many test items have been set up and implemented.

In addition to ensuring the above four characteristics, Lisson also has the ability to prevent problems, resolve problems invisible, and prevent problems from recurring. This will be sent to you in future articles-cosmetic packaging material tubes encounter problems How to do?
