Cosmetic injection bottles are both an industry and a culture. In today's financial environment, cosmetics are the sunrise product positioning in the market and cannot be shaken. However, the level of customized manufacturers of cosmetic bottles is uneven. Therefore, after receiving the goods, it is necessary to check not only whether the quantity is complete, but also whether the quality is checked. How to check whether the quality of cosmetic injection bottles passes, and what standards are there?
1. appearance: visual inspection is given priority to, under sufficient light environment, with normal vision, 20cm-30cm in front of the eye to check whether there are defects, sundries, scratches and other quality problems on the surface.
2. size: Measure the sample with a ruler or a vernier caliper with an accuracy of 0.02mm and record the value to see if it meets the size standard.
3. Weight: Weigh the sample with a 0.1g scale and record the value to see if it meets the agreed size standard.
4. capacity: weigh the sample on a balance with a dividing value of 0.1g, remove the gross weight of the bottle, inject tap water into the sample bottle to the full mouth and record the value (directly inject paste or convert the density of water and paste if necessary).
5. Printing adhesion and bronzing (silver) fastness: ① Use 3M810 to test the printing and bronzing (silver) parts of the tape cover, smooth them so that the cover parts are free of bubbles, and then quickly tear them off. The printing parts are continuously done 3 times and the bronzing (silver) parts are continuously done 2 times. ② Wipe the gauze soaked with disinfectant alcohol back and forth twice on the printing site.
6. Flip performance: at room temperature, flip up and close the flip by hand 200 times without breaking, and the tightness and tightness are the same as those before the flip.
7. bottle cap matching test: the bottle cap fits smoothly and does not slip, the matching mode of bottle and cap is divided into thread type and buckle type, and the matching gap between buckle type bottle and cap is ≤ 0.4mm; Fit gap between threaded bottle and cap: 0.1mm ≤ gap ≤ 0.6mm.
8. Tightness test: ① Fill the bottle with water of the same weight or volume as the net content of the product, place it in a vacuum box, vacuum to-0.05MPa for 5 minutes, and there should be no water leakage. ② If the above vacuum test is not passed, add water with the same weight or volume as the net content of the product in the bottle for 24 hours, and there should be no water leakage. (This method is only for the jar class).
9. drop test: add water with the same weight or volume as the net content of the product into the bottle, cover the bottle, and hold it to the specified height: drop down along the 45-degree bevel bottle cap, lay it flat and freely, and drop the bottom vertically to the cement floor three times each, without cracking, leakage, component separation, etc. Net content of product identification> 200 ml/g falling height is 1.2m; Net content of product identification ≤ 200 ml/g falling height is 1.5m.
10. heat and cold resistance test: ① heat resistance test: add water with the same weight or volume as the net content into the sample bottle, and place it sideways in a constant temperature box (48±1 ℃) for 24 hours, without cracking, deformation, discoloration, water leakage, etc. Cold resistance test: the sample bottle is added with the same weight or volume of water as the net content, and after 24 hours of lateral placement in the refrigerator (-10 ℃ to -15 ℃), there is no rupture, deformation, discoloration, water leakage and other phenomena.
11. Bar code readability: The bar code can be clearly and accurately read out at one time through the bar code instrument. Judgment of qualified or unqualified 5.4 batch by batch inspection: for appearance inspection items and functional inspection items, according to the results of sample inspection, if the number of unqualified products found in the sample is less than or equal to the qualified judgment number, the batch is judged as qualified; if the number of unqualified products found in the sample is greater than or equal to the unqualified judgment number, the batch is judged as unqualified.

PET (polyethylene terephthalate) hard sheet. PVC (polyvinyl chloride) hard sheet. PS (polystyrene) hard sheet, PS hard sheet low density, poor toughness, easy to burn, burning will produce styrene gas (a harmful gas), so it is generally used to produce a variety of industrial blister tray. PVC hard sheet has moderate toughness and is not easy to burn. When burning, chlorine gas will be generated, which will have a certain impact on the environment. PVC is easy to heat and seal. Sealing machine and high frequency machine can be used to seal the edge. It is the main raw material for the production of transparent plastic products. Blister is a kind of plastic processing technology. The main principle is to heat the flat plastic hard sheet to soften, and then use vacuum adsorption on the surface of the mold, and then form after cooling. It is widely used in plastic packaging, lighting, advertising, decoration and other industries.

Cosmetic packaging material classification?
What are the main cosmetic packaging materials? How is it classified?? For example, plastic bottles are also one of the cosmetic packaging materials. Cosmetic packaging material is a kind of packaging material industry, divided into the whole packaging material and part of the packaging material. The overall packaging materials are usually provided by cosmetics manufacturers with drawings or general requirements and submitted to packaging materials manufacturers for production, while some packaging materials are divided into more subtle, more specific situations and requirements, and are divided into local printing, bottle packaging materials and bottle body packaging materials. Depending on the type of cosmetic packaging, you can also outsource some small accessories. The cosmetics packaging material industry and cosmetics are closely linked. Nowadays, the overall homogeneity of the cosmetics industry has enhanced the value of packaging materials. In recent years, industry insiders have also called for low-carbon and green packaging material services. 1---PET? Its main characteristics are high air tightness, good compressive strength, high water resistance and very transparent. Its transparency is as high as 95%, which is higher than that of other commonly used plastic packaging containers, but it is not heat resistant. It is often used in food, beverage bottles and cosmetic packaging materials. It is precisely because of its high air tightness and the packaging container has no hairs and pores, so it is used to make a container for packaging alcohol. 2---HDPE The Chinese name is high-density polyethylene, which is commonly known as high-density PE. It is the second material on the international material label number. Its main characteristic is good acid and alkali resistance. The products made from it are translucent, heat resistance is not very good, use it to make packaging containers hairy pores. It is often used in chemical packaging containers such as pharmaceutical bottles and cosmetic bottles. 3---PVC The Chinese name is polyvinyl chloride, which is No. 3 material on the international material label number, Its main characteristics are transparent and heat-resistant. Before the advent of early PET, it replaced PET and was used in mineral water, fruit juice and other beverages. At present, its main function is to manufacture water pipes for building materials and enameled wires for external lines. The container made of it will have pores, so it is not suitable to use it to hold wine. 4---LDPE The Chinese name is low-density polyethylene, which is also known as low-density PE. It is No. 4 material on the international material label number. Because of its low molecular density, it is softer than HDPE. The products processed with it are translucent, heat-resistant and have fine pores, but it has good acid and alkali resistance. Containers made of this material are often used in chemical industries such as facial cleanser, salad, glue bottle, cosmetic bottle hose, etc. 5---PP The Chinese name polypropylene is No. 5 material on the international material label number. It is a high-density material. The products processed with it are translucent, heat-resistant, impact-resistant, acid and alkali-resistant, but have fine pores. It is commonly used in hot filling packaging of food, microwave cooking tableware, can hold high temperature food and general household face plate, mouthwash cup and other daily necessities microwave-grade processing such as: measuring cup. 6---PS The Chinese name is polystyrene, which is No. 6 material on the international label material number. The products processed with it are transparent, well sealed, but fragile and heat-resistant. It is commonly used in sealed cans, Processing of food boxes. 7---PC It is in the international label material number is seven material, with its processing products made of transparent, high heat resistance, not easy to break. It is often used in the processing of milk bottles, distillation barrels, heat-resistant barrels and medicine bottles.
Cosmetic packaging materials commonly used materials
1. ABS: ABS is an engineering plastic, not environmentally friendly, high hardness, can not be directly in contact with cosmetics, food, in acrylic cosmetics packaging materials are generally the inner cover, shoulder cover material. The color is yellow or milky white. 2. PP, PE: PP and PE are environmentally friendly materials that can be directly in contact with cosmetics and food. They are the main materials for filling organic skin care products. The materials are white and translucent. According to different molecular structure, can achieve three different degrees of soft and hard. 3. PET: PET is an environmentally friendly material that can be directly in contact with cosmetics and food. It is the main material for filling organic skin care products. PET is soft and its natural color is transparent. 4. PCTA, PETG: PCTA and PETG are environmentally friendly materials that can be directly in contact with cosmetics and food. They are the main materials for filling organic skin care products. The materials are soft and transparent. PCTA and PETG are soft and easy to scratch. And it is not commonly used to print more often. 5,: AS hardness is not high, crisp (knock when there is a crisp sound), transparent color, and the background color blue can be directly in contact with cosmetics, food, in ordinary lotion bottles, vacuum bottles are generally the material of the bottle body, can also be made of small capacity cream bottles. It is transparent. 6. Acrylic: The material is hard, transparent, and the background color is white. And acrylic in order to maintain a transparent texture is often sprayed inside the outer bottle, or colored during injection molding.
Under the background of rapid economic development, the consumption concept of young consumers has changed with the improvement of living standards.
In addition to replacing packaging materials
2021 is the first year of my country's "14th Five-Year Plan" and a turning point for the cosmetics industry. In the past two years, the competition in the cosmetics industry has intensified, and the momentum of environmental protection has become stronger. Many companies have actively or passively joined the environmental protection cause. While seeking a way out for their own sustainable development, they have also contributed to the environment. Take Arcade Beauty, a small sample manufacturer of beauty products, as an example, recently announced a news that it has developed a recyclable PE (polyethylene) packaging bag for L'Oreal Paris, L'Oreal's largest beauty brand. Coincidentally, last week, L'Oreal announced that it will launch innovative cosmetic packaging bottles, which are scheduled to go into production in 2025. Combined with the "environmental actions" of other brands, Xiaobian found that replacing packaging materials is the way they usually deal with it, such as using soluble packaging, 100 percent recycled plastic, and so on. Previously, foreign media reported that some brands have developed the use of bacterial cellulose to make cosmetics plastic packaging paper instead of this technology. Bacterial cellulose, also known as "microbial cellulose", has relatively good biological adaptability and degradability, and is a cutting-edge technology to reduce environmental pollution. It can be seen that packaging environmental protection is an inevitable trend in the development of cosmetics, and it is also an important technology for brands to enhance their competitiveness. In fact, in addition to packaging, we can also start from raw materials, technology, logistics and other aspects. Like HEYAN (HERA) through the improvement of the formula, to achieve more in line with environmental requirements. One of them is that the main product, HERA Black Gold Lasting Foundation, is palm oil grown and produced in a sustainable way certified by the Roundtable Initiative for Sustainable Palm Oil (RSPO,Roundtable of Suatainable palm Oil). . In addition, Old Spice, P & G's deodorant brand, has a deodorant lotion called Clean water. Its paper tube packaging is made of recycled paper and adopts a "push up" design to reduce weight. The packaging of the product is made of 90% post-consumer recycled materials. It is reported that this is the most environmentally friendly product of P & G's men's beauty products to date. We know that reducing carbon emissions is the most direct way. Therefore, if the logistics and transportation are low-carbon, the burden on the environment will inevitably be greatly reduced. For example, Amore Pacific's brand has greatly reduced the use of cushioning materials and turned to inflatable airbags instead of foam. At the same time, it also uses plant fiber tape that can be naturally degraded in a short time instead of traditional tape. Compared with before, the packaging and transportation process is much more environmentally friendly. All in all, environmental protection has become a topic of heated discussion today. Today's consumers, in order to express their support for environmental protection, basically have a "good impression" of this kind of cosmetics ". Therefore, regardless of the size of their own enterprises, more snacks on environmental issues is always right!
