What is the chemical composition of the gasket in the cream jar, can I get the MSDS certificate?
In addition to a prototype suction cup and bottle mouth sealing seal, the cream bottle also has a plastic gasket, which is thin and tears when used. Please inform the person about the chemical composition of this gasket and whether it can issue MSDS (Chemical Safety Certificate).

Should be polyethylene, or polyvinyl chloride, the former is non-toxic, the latter is toxic at high temperatures
Can the cosmetic bottle be injection molded? How to injection?
can. The thickness of the bottle wall of a cosmetic bottle is generally an injection molding such as a cream bottle, and the bottle wall is generally a blow molding such as a shampoo bottle. The cap is typically injection molded. Injection molding machine and mold opening, the general company injection mold master will be the upper mold, the lower mold, start production
What kind of material is the plastic bottle of cosmetics?
 1. PET material is environmentally friendly material, with high barrier property, light weight, non-breaking characteristics, chemical resistance, and strong transparency. It can be made into pearlescent, colored, magnetic white, transparent, and widely used in the installation of gel water. The bottle mouth is generally standard 16#, 18#, 22#, 24# caliber, and can be used with the pump head.
2, the material of the plastic bottle is usually PP, PE, K material, AS, ABS, acrylic, PET and so on.
3, acrylic material for injection molding bottles, chemical resistance is poor, generally can not directly paste the paste, need to be equipped with a liner barrier, filling is not too full, to prevent the paste from entering between the liner and the acrylic bottle, In order to avoid cracking, the packaging requirements are higher during transportation, it is particularly obvious after scratching, the permeability is high, and the upper wall is very thick, but the price is quite expensive.
4, usually used in cosmetic containers, thicker cream bottles, caps, stoppers, gaskets, pump heads, dust covers for injection molding; PET blowing bottles for two-step molding, tube blanks for injection molding, finished packaging For blowing bottles. Other emulsion bottles such as thinner containers and washing bottles are blown bottles.
5, AS, ABS: AS transparency is better than ABS, and the toughness is better.
6, the order quantity is generally 3,000 - 10,000, can be customized color, usually do primary color matte and magnetic white, or add pearl powder effect, the same color masterbatch with the bottle and cover, but sometimes due to the bottle and cover The materials used are different, and the colors displayed are somewhat different.
7, silk screen has ordinary ink and UV ink, UV ink effect is good, shiny and three-dimensional sense, in the production should first confirm the color, the screen printing effect will be different in different materials.
8, bronzing, hot silver and other processing technology and printing gold powder, silver powder effect is different, hard material and smooth surface is more suitable for hot stamping, hot silver, soft surface hot stamping effect is not good, easy to fall off, hot gold and silver luster Better than gold and silver.
9, silk screen film to the negative film, the graphic effect is twilight, the background color is transparent, hot stamping, hot silver process to produce a positive film, the graphic effect is transparent, the background color is twilight. The text and pattern ratio should not be too small or too thin, otherwise the effect will not be printed.
10, the bottle cap is generally equipped with internal gaskets, pull caps, inner plugs, very few with a small spoon or dropper, which is mainly considering its sealing and ease of use.

Cosmetics packaging inspection methods and testing instruments
        As a fashionable consumer product today, cosmetics not only need exquisite packaging, but also need to be optimally protected during transportation or shelf life. Combining the needs of cosmetics packaging inspection and application, the inspection items and inspection methods will be summarized, with a view to helping the cosmetics production companies and cosmetics packaging supply companies in terms of packaging inspection and quality control.
        First, cosmetics transport packaging testing Cosmetics after transportation, shelf display and other aspects to reach the consumers in good hands, you need to have a good transport packaging. At present, the shipping and packaging of cosmetics is mainly based on corrugated boxes. The main testing index is the compressive strength and stacking test of the carton.
        1, the carton compressive strength test.
        2. Carton stacking test The carton needs to be stacked during storage and transportation. The lowest layer of the carton bears the pressure of the upper multiple cartons. In order not to collapse, it must have suitable compressive strength after stacking. It is important to double check the stacking and maximum crushing forces.
        Second, cosmetics packaging printing quality testing Cosmetics have a good visual beauty, are beautifully printed, for its print quality testing is more important. At present, the routine items for the inspection of cosmetics printing quality are the abrasion resistance (anti-scratch performance) and adhesion fastness of printing ink layers, and color discrimination. People usually observe the colors in daylight, so the elaborate color analysis work in industrial production requires the illumination light source to have a spectral power distribution with approximately true sunlight, namely the D65 standard light source specified in the CIE. However, in the color matching process, there is a very special phenomenon: the sample and the sample will appear in the same color under the first light source, and under a different light source there will be a color difference, the so-called metachromatic phenomenon, so the selection criteria The light source must have dual light sources.
        Third, cosmetics sticker labeling The application of self-adhesive labels in cosmetics packaging is relatively extensive. The testing items mainly focus on the adhesive properties of self-adhesive labels (adhesive or pressure sensitive adhesive). The main testing items are: The initial viscosity, holding performance, peel strength (peeling force) three indicators. Fourth, cosmetic packaging packaging performance testing Barrier packaging performance is one of the important cosmetic packaging testing items. Barrier property refers to the barrier effect of packaging materials on gases, liquids, and other permeants. Barrier performance is an important factor affecting the quality of products during shelf life. The unsaturated bonds in the cosmetic ingredients are prone to rancid deterioration due to oxidation, and the loss of water tends to make the cosmetic dry and harden. At the same time, the maintenance of the aromatic odor in cosmetics also plays a crucial role in the sale of cosmetics. Barrier performance testing includes cosmetic packaging testing of oxygen five, water vapor, and aromatic gas transmission performance.
        1. Oxygen transmission rate test. This indicator is mainly used for the detection of oxygen transmission rate of films, composite films, and cosmetic packaging bags or bottles used in cosmetics packaging.
        2, water vapor transmission rate testing, mainly used for cosmetics packaging film materials and bottles, bags, cans and other packaging containers for the determination of water vapor transmission rate. Through the determination of the water vapor transmission rate, technical indicators such as control and adjustment of packaging materials can be achieved to meet the different needs of product applications.
        3, Baoxiang performance testing, this indicator is very important for cosmetics, once the loss of cosmetic fragrance or change will affect the product sales. Fourth, cosmetic packaging and packaging materials, other physical and mechanical indicators testing Cosmetic packaging mechanical properties for cosmetics during packaging processing, transportation, shelf plays a very important role. Its quality directly determines the safety of food in circulation. Summary All test items mainly include: tensile strength and elongation, composite film peel strength, heat seal strength, seal and leakage, impact resistance, surface smoothness properties of the material and other indicators
        Fifth, cosmetics packaging material thickness test Cosmetic packaging materials (film or sheet) thickness is uniform, is the basis for testing the performance of the film. The uneven thickness of the film not only affects the tensile strength and barrier properties of the film, but also affects the subsequent processing of the film. There are several methods for measuring thickness, which are generally classified into non-contact and contact: non-contact including ray, eddy current, and ultrasonic, etc., and contact industry, also known as mechanical thickness measurement, which is divided into point contact type and surface type. Contact type. At present, the laboratory test of the thickness of the cosmetic film uses the mechanical surface contact test method, which is also used as the thickness arbitration method.
        VI. Sealing and Leak Detection of Cosmetic Packages Sealing and leak detection of cosmetic packaging refers to the property of packaging bags to prevent other substances from entering or contents from escaping. There are two methods commonly used in the detection method, water pressure reduction method and positive pressure detection method.
       7. Analysis of cosmetics packaging headspace: Oxygen and water vapor are the main factors affecting the shelf life of most products. The study found that controlling the proportion of gas components in cosmetic packaging can effectively extend the shelf life of products or improve the preservation quality. When cosmetics are finished filling There will be a small amount of air remaining in the package. To detect and analyze the oxygen or headspace gas in the package, a headspace analyzer is used.
        Eight, cosmetics bottles packaging testing equipment Bottle packaging is now used in packaging more packaging. The size of the cap locking and opening torque is one of the process parameters that the production unit controls offline or online. Whether the torque value is appropriate or not has a great influence on the intermediate transportation of the product and the final consumption. Detection of cap opening and locking force requires detection with the NLY-20 torque meter.

 Reduce the volume and contents of the packing Alerter l'administrateur Recommander à un ami Lien de l'article 

 This is in major done to reduce the volume and contents of the packing. Having fresh food in the house is what any person wants, this is what the vacuum packaging helped in the field of food packaging. this is a very important aspect in the pakiranje hrane (food packaging) process as it ensures the level of purity of the food that is to be used in consumption and most of them are the ready-to-eat ones which has to be dealt with extra care and handling.Prior to sealing of any article in the food packing, especially, there has to be a process where there can be nullification of the air content in the packets.
This vacuum packaging helps in reducing the jeopardy of the fungi or aerobic bacteria to attack the stuff that has food and other healthily required items. These are used commonly in the packaging of the long term use of the stored foods like for example cereals, nuts, meat, cheese etc.. Food safety is what is necessary and that perhaps you get it with intact and viable food packaging in such companies. This is what happens in the vacuum packaging process. Also at times due to poor oxygen environment it happens that anaerobic organisms( that grow in absence of oxygen) can tend to proliferate but even for this there are definite processes prior the completion of the packing.
 There are varied shapes of plastic bags availed in the industrial level, without adulteration in the plastics, which can be safely used for vacuum packaging.vakumsko pakiranje (vacuum packaging) for even the fresh veggies and soups is possible but for a shorter term and it has to intend for better services as they cannot restrict the water to get in for a longer period. So if you ever come across with the hot dog from your favorite outlet then make sure that they are well packed without bubbles in them which surely can guarantee what you are eating. The intention for this is to get the excess oxygen completely removed from the containers and packets. This includes all types of packing processes, be it the flexible ones or the rigids. There are thus, different chambers of machines for both snack packaging and for liquid packaging
