Maypak Packaging Specialized in Cosmetic Packaging Containers and Cosmetic Bottles Wholesale
" Common cosmetic packaging materials include Plastic Cosmetic Bottles, Glass Cosmetic Bottles, Plastic Cosmetic Tubes, etc. Packaging materials of different materials have different
characteristics and are suitable for cosmetics of different textures and ingredients. Some cosmetics require special packaging due to their special ingredients to ensure the activity of the
ingredients. Dark glass bottles, airless pumps, metal tubes, and ampoules are commonly used special packaging. "
- - - - - - - - - - Test Items: Barrier Performance - - - - - - - - - -
The barrier performance of packaging is one of the important testing items for cosmetic packaging. Barrier properties refer to the barrier effect of packaging materials on gases, liquids and other permeable substances. Barrier properties are an important factor affecting the quality of products during their shelf life.
The unsaturated bonds in cosmetic ingredients can easily cause rancidity and deterioration due to oxidation. The loss of water can easily cause cosmetics to dry and harden. At the same time, maintaining the aromatic smell in cosmetics also plays a vital role in the sales of cosmetics. Barrier performance testing includes testing the oxygen, water vapor, and aromatic gas permeability of cosmetic packaging.
1. Oxygen transmission rate detection. This indicator is mainly aimed at the oxygen transmission rate detection of films, composite films and overall packaging of cosmetic packaging bags or bottles used in cosmetic packaging.
2. Water vapor transmission rate testing, mainly used to measure the water vapor transmission rate of cosmetic packaging film materials and packaging containers such as bottles, bags, cans, etc. Through the measurement of water vapor transmission rate, the technical indicators of packaging materials and other products can be controlled and adjusted to meet the different needs of product applications.
3. Fragrance retention performance testing. This indicator is very important for cosmetics. Once the fragrance of cosmetics is lost or changed, the sales of the product will be affected. Therefore, it is very important to test the fragrance retention performance of cosmetic packaging.
- - - - - - - - - - Test Items: Strength Test - - - - - - - - - -
Strength testing methods include product packaging design material tensile strength, composite film peeling strength, heat sealing strength, tear strength, puncture resistance and other indicators. Peel strength, also known as composite system strength, is used to detect the bonding strength between layers in the composite film. If the bonding strength requirement is too low, problems such as leakage caused by separation between layers will easily occur during packaging use. . Heat sealing strength is used to detect the strength of the seal. During the storage and transportation management of the product, once the heat sealing strength is too low, it will directly lead to problems such as cracking of the heat seal and leakage of contents. Puncture resistance is an indicator for risk assessment of the packaging's ability to resist puncture by hard objects.
Strength testing will use an electronic tensile testing machine. The tensile testing machine independently developed and produced by Shandong Puchuang Industrial Technology Co., Ltd. can complete a variety of experimental tests at the same time (tensile strength, peel strength, puncture performance, tear strength, etc.); heat sealing test The instrument can accurately test the heat sealing strength, heat sealing pressure, etc. of packaging materials.

Thickness is the basic capability indicator for detecting thin films. Uneven thickness distribution will not only directly affect the tensile strength and barrier properties of the film, but will also affect the subsequent development and processing of the film.
Whether the thickness of cosmetic packaging materials (film or sheet) is uniform is the basis for testing various properties of the film. Uneven film thickness will not only affect the tensile strength and barrier properties of the film, but will also affect the subsequent processing of the film.
There are many thickness measurement methods, which are generally divided into non-contact and contact methods: non-contact includes ray, eddy current, ultrasonic wave, etc.; contact type is also called mechanical thickness measurement in the industry, which is divided into point contact and surface. contact type.
Currently, laboratory testing of cosmetic film thickness uses mechanical surface contact testing, which is also used as an arbitration method for thickness.

The sealing and leakage detection of cosmetic packaging refers to the characteristics of the packaging bag to prevent other substances from entering or the contents from escaping. There are two commonly used detection methods:
1. Water Pressure Reduction Method:
The test process is as follows: put an appropriate amount of distilled water into the vacuum tank, put the sample into the vacuum tank under the pressure plate so that the package is completely immersed in the water; then set the vacuum pressure and time of the test, start the test, and evacuate the vacuum chamber. Create a pressure difference between the inside and outside of the sample immersed in water, and observe the escape of gas in the sample to determine the sealing performance of the sample.
2. Positive Pressure Detection Method:
By applying pressure to the inside of the package, the pressure resistance, sealing degree and leakage indicators of the flexible packaging are tested to achieve the purpose of testing its integrity and sealing strength.
