Introduction of transparent plastic cosmetic tube

2021-11-08

Transparent plastic cosmetic tube is a kind of transparent white plastic packaging container formed by blow molding. The manufacturer of cosmetic tube is processed by injection molding to form an intermediate product cosmetic tube blank, and then blow molded to form a plastic cosmetic tube. It is the two-step forming principle. Transparent plastic cosmetic tube is a transparent cosmetic tube blank formed by injection molding of special materials made of polyester. 

The transparent cosmetic tube blank is blow-molded under specific pressure and temperature conditions. The volume in the gun mold of the mold is The specifications of the mold are expanded to obtain a transparent plastic cosmetic tube of corresponding height and thickness. At present, transparent plastic cosmetic tubes are mostly used for packaging cosmetics and skin care products.

For wholesale plastic cosmetic tubes, manufacturers of cosmetic tubes generally use PE, PP, PET and other materials, which have the advantages of not being easily damaged, good sealing performance, moisture-proof, hygienic, and meeting the special requirements of pharmaceutical packaging. It can be directly used for cosmetics packaging and is an excellent packaging container

PET cosmetic tube

Hard quality, good toughness, high strength, bright surface, environmental protection and non-toxic, transparent and multi-color sheets. The disadvantage is that PET high-frequency heating is more difficult, and the price is slightly more expensive than PVC. This material is often replaced by users who require high-end and environmentally friendly products. PET materials are generally used to package skin care products and plastic cosmetic tubes in the cosmetics industry.


When blowing PET plastic cosmetic tube, what problems will cosmetic tube manufacturers encounter? When plastic materials are used to manufacture plastic cosmetic tubes, the following problems are often encountered, so today cosmetic tube manufacturers will summarize the situations and solutions that are very easy to do in the whole process.

1. The current thickness situation, deal with: the pre-blowing time must be delayed, or the pre-blowing working pressure must be reduced, and the total flow rate must be reduced.

2. To deal with the current conditions of thickness: use problem one to solve the inverse problem.

3. There will be wrinkles and processing on the lower side of the short board: the pre-blowing is too late or the pre-blowing working pressure is too low, or the billet here is not well refrigerated.

4. White bottom, treatment: The key reason is the low temperature of the cosmetic tube; the other is too much skin rash, pre-blowing time is too early or pre-blowing pressure is too high.

5. The bottom of the cosmetic tube appears high-powered, and there is too much material at the bottom of the cosmetic tube. Treatment: pre-blowing is too late and pre-blowing pressure is too low.

6. There are wrinkles at the bottom of the cosmetic tube, and the temperature at the bottom is too high (the inlet is not cold). Treatment: pre-blowing too late with low working pressure, and the total flow is very small.

7. The turbidity of all cosmetic tubes is low. Treatment method: insufficient refrigeration.

8. Partially white: Too much salad, processing: The temperature is too low, or too early to blow in advance.

9. The axial force at the bottom of the PET plastic cosmetic tube is related to the temperature, drawing, pre-blowing and high-pressure blowing of the cosmetic tube. Treatment method: first reduce the temperature of the cosmetic tube blank; speed up the drawing speed; check the gap between the support rod head and the bottom mold; delay the pre-blowing to reduce the pre-blowing pressure; delay the high-pressure blowing; check the cosmetics after the solution Whether the tube blank will continue to receive axial force.


pp cosmetic tube

The material is particularly soft, good toughness, environmentally friendly, non-toxic, and high temperature resistant. It is often used as packaging for cosmetics or other skin care products; but its plasticity is poor. For cosmetic tube manufacturers, it is difficult to process and has poor surface gloss. The color becomes lighter during processing, and it is used to make disposable plastic packaging.


PVC cosmetic tube

It has soft quality, strong toughness and good plasticity. The cosmetic tube manufacturer can make it into transparent and various colors. It is commonly used for plastic cosmetic tubes of transparent PVC packaging and cosmetic products.

The main development direction of transparent plastic cosmetic tubes is the packaging of cosmetics. Another trend is to replace recycled plastics with biodegradable plastics.


Ordinary cosmetics and detergent packaging containers are mostly made of high-density polyethylene. In order to meet the packaging requirements of different products, the materials used for plastic cosmetic tubes are also becoming more abundant. Since the transparent plastic cosmetic tube container allows consumers to see the contents clearly, consumers have more and more requirements for transparent PP plastic cosmetic tube container, and transparent polypropylene is the main material to meet this requirement, pp transparent The development of packaging cosmetic tubes is a hot spot for wholesale plastic cosmetic tube packaging in recent years. Highly transparent polypropylene containers have good transparency and gloss, and are highly appreciated and popular. How to stand out in the modern market with fierce competition and constantly evolving sales methods, in addition to product innovation and high-quality and fast service, cosmetic tube manufacturers have become more and more important in transparent packaging. From a market point of view, packaging is a formal product in the overall product, and it is a very important part of the content. Through it, consumers can have a desire to buy, thereby stimulating consumption. Facts have proved that transparent packaging can often stimulate consumption and form purchasing power. Transparent packaging includes full transparent packaging and partially transparent packaging. It is through transparent packaging materials that partially or fully display the product form of the cosmetics inside, allowing buyers to directly see the image, color and quality of the cosmetics, which can reflect the natural beauty of the product. It is also convenient for customers to identify and purchase. Such as transparent plastic cosmetics cosmetic tubes are clear at a glance, so consumers can't help but donate, and sales have soared.
