The cosmetic packaging testing projects mainly include: barrier performance testing (gas permeability test and water vapor permeability test), friction coefficient (material surface smoothness), tensile strength and elongation, peel strength, heat seal strength (heat seal strength), sealing and leakage testing, impact resistance testing, thickness testing, solvent residue testing, printing quality testing, etc. In combination with the cosmetic packaging testing needs, Jinan Labthink Technology Co., Ltd. (Labthink) has sorted out the information of cosmetic packaging testing instruments as follows, in order to help the quality testing of cosmetic packaging and dairy companies.

1. Barrier performance testing of cosmetic packaging testing instruments
Barrier property refers to the barrier effect of packaging materials on permeates such as gases (such as oxygen) and liquids (water vapor). Barrier performance is an important factor affecting the quality of products during the shelf life. The instrument information list is as follows:

Host and satellite mode, one host can be connected to nine satellites, and thirty samples can be tested simultaneously.

This series includes TSY-T1H, TSY-T1L, TSY-T3 and other models.

2. Cosmetic packaging strength test
Strength test includes indicators such as packaging material tensile strength, composite film peel strength, heat seal strength, tear strength, and puncture resistance. Tensile strength refers to the maximum stress value that the material can withstand before breaking. Through testing, it can effectively solve the packaging damage and breakage caused by external force due to insufficient mechanical strength of the selected packaging materials. Peel strength is also called composite strength. It is to test the bonding strength between layers in the composite film. If the bonding strength is too low, it is very easy to cause leakage and other problems such as separation between layers during packaging use. Heat seal strength is to test the strength of the seal. During the storage and transportation of the product, once the heat seal strength is too low, it will cause problems such as cracking of the heat seal and leakage of contents. Puncture resistance is an indicator for evaluating the ability of packaging to resist puncture by hard objects.
The corresponding testing instrument information is as follows:
1. XLW series intelligent electronic tensile testing machine: peeling, tensile test, heat sealing strength test, and tearing performance professional test for films, composite films, adhesives, adhesive tapes, etc. This series has XLW, XLW (B), XLW (M), XLW (PC), XLW (G) and other models.

V. Impact resistance test of cosmetic packaging
Test the impact resistance of packaging materials to ensure that the selected packaging materials can effectively protect the products. There are two test methods for impact resistance test: dart impact and pendulum impact.
1. BMC-B1 dart impact tester: free falling dart test method, which determines the impact mass and energy of plastic film or sheet when the sample is broken under the impact of free falling dart at a given height.

The hemispherical punch of the film impact tester impacts and passes through the film sample at a certain speed, and the energy consumed by the punch is measured to evaluate the film’s ability to resist pendulum impact.

VI. Tear performance test of cosmetic packaging:
During the storage and transportation of products, the packaging may be torn due to external forces. Sufficient tear propagation force can reduce tear transmission and avoid packaging leakage
SLY-S1 tearing tester: Elmendorf method, used for tear resistance test of films, thin films, paper, cardboard and other materials.
