How to test the performance of cosmetic packaging

Cosmetic packaging testing items mainly include: barrier performance testing (gas transmission rate test and water vapor transmission rate 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.

Barrier performance testing of cosmetic packaging testing equipment

Barrier property refers to the barrier effect of packaging materials on gas (such as oxygen), liquid (vapor) and other permeates. Barrier performance is an important factor affecting the quality of products during the shelf life.

1. Differential pressure and equal pressure dual method test, used for the gas permeability test of plastic film, composite film and other films, sheet materials and finished containers. Three-cavity independent, automatic, temperature control, arbitrary temperature data fitting, support for local area network data centralized management, patented product.

2. Coulomb principle, isobaric method to test the oxygen permeability of films, sheet materials, bottles, bags, cans, boxes and other packaging containers.

3. It is used for the determination of water vapor transmission rate of film, sheet material and packaging containers such as bottles, bags, cans and boxes.

Cosmetic packaging strength testing

Strength testing includes packaging material tensile strength, composite film peel strength, heat seal strength, tear strength, puncture resistance and other indicators. Tensile strength refers to the maximum stress that the material can withstand before it breaks. Testing can effectively solve the packaging damage and fracture caused by external force due to insufficient mechanical strength of the selected packaging material. Peel strength, also called composite strength, is to detect the bonding strength between layers in the composite film. If the bonding strength is too low, problems such as leakage caused by separation of the layers during packaging use are very likely to occur. Heat seal strength is to detect the strength of the seal. During the storage and transportation of the product, if the heat seal strength is too low, it will cause problems such as cracking of the heat seal and leakage of the contents. Puncture resistance is an index for evaluating the puncture resistance of packaging against hard objects.

The corresponding testing instrument information is as follows:

1. Film, composite film, adhesive, adhesive tape, etc. peeling, tensile test, heat-sealing strength test, tearing performance professional test.

2. Film, composite film, adhesive, adhesive tape, etc. peeling, tensile test, heat sealing strength test; standard specification 200n (100n, 50n, 30n), micro-printing, computer communication interface.

3. Heat sealing tester: sample preparation for film heat sealing strength test, pressure, temperature and time are adjustable.
