What methods are generally used for cosmetic packaging inspection?

Cosmetic packaging must be exquisite and meet the visual aesthetics, and the structure and other aspects must meet the standards, so its quality inspection is particularly important, and the inspection method is an important technical basis for inspection activities. At present, the routine items of cosmetic packaging printing quality inspection mainly include the abrasion resistance of the printing ink layer (anti-scratch performance), ink adhesion fastness and color discrimination inspection. During the inspection process, the packaging products do not appear ink drop or deinking, etc. Qualified product. There are different inspection standards and methods for different cosmetic packaging materials. Let’s take a look at the inspection methods and standards for various packaging.

First, ensure that the materials used must be hygienic and non-toxic:

All materials should have a certain degree of chemical stability, can not interact with the products it contains, and are not easy to change color and fade under light. New product development packaging materials are green and environmentally friendly materials, and are tested for compatibility with the material body to ensure that the material body will not deteriorate, delamination, color discoloration and thinning; for example: mask cloth, air cushion sponge, gradual special craft bottle, etc. .

Second, the inspection standards of different packaging materials:

1. the inner plug
Structure: There are no protrusions that can cause damage to the user, the threads are not misaligned, and the bottom is flat.
Impurities (internal): There are no impurities in the bottle that seriously pollute the product. (Hair, insects, etc.).
Impurities (external): No impurities (dust, oil, etc.) that may contaminate the product.
Printing and content: correct, complete and clear, and the script is consistent with the standard sample.
Bubbles: no obvious bubbles, ≤3 bubbles within 0.5mm in diameter.
Structure and assembly: Functionality, good fit with cover and other parts, clearance ≤1mm, no leakage.
Size: ±2mm within the limit
Weight: within the limit range ± 2%
Color, appearance, material: in line with standard samples.

2. Plastic bottle
The body of the bottle should be stable, the surface should be smooth, and the thickness of the bottle wall should be basically uniform, without obvious scars, deformation, cold bursts and cracks. The bottle mouth should be straight and smooth, no burrs (burrs) should be used, and the thread and bayonet fitting structure should be intact and straight. The fit between the bottle and the cap should be tight, with no slippery teeth, loosening, and no leakage. The inside and outside of the bottle should be clean.
Structure: No protrusions that cause user injury
Impurities (internal): There are no impurities in the bottle that seriously pollute the product. (Hair, insects, etc.).
Impurities (external): No impurities (dust, oil, etc.) that may contaminate the product.
Printing and content: correct, complete and clear, and the script is consistent with the standard sample.
Surface scratches, breakages, etc.: There are no scratches, cracks, dents, etc. on the surface.
Structure and configuration: functionality. It fits well with the inner plug/cover and other parts.
Key dimensions: ±2mm within the limit
Printing adhesion: 3M-810 tape, pull hard at 45°-90°, and there is no obvious separation of the text part.
Weight: within the limit range ± 2%
Color, appearance, material: in line with standard samples.

3. Lip tube
Structure: No protrusions that cause user injury
Impurities (internal): There are no impurities in the bottle that seriously pollute the product. (Hair, insects, etc.).
Impurities (external): No impurities (dust, oil, etc.) that may contaminate the product.
Printing and content: correct, complete and clear, and the script is consistent with the standard sample.
Surface scratches, breakages, etc.: There are no scratches, cracks, dents, etc. on the surface.
Structure and configuration: functionality. The parts cooperate well.
Critical dimensions: within limits
Printing adhesion: 3M-810 tape, pull hard at 45°-90°, and there is no obvious separation of the text part.
Weight: within the limit range ± 2%
Color, appearance, material: in line with standard samples.

4. Stickers

Printing and content: the text is correct, complete and clear, and the manuscript conforms to the standard.
Document color: in line with the standard sample.
Surface scratches, breakages, etc.: No scratches, cracks, tears, etc. on the surface.
Impurities: no visible impurities (dust, oil, etc.)
Color, appearance, material: in line with standard samples.

5. Powder base

The surface of the box should be smooth and straight, and there should be no obvious scratches, burrs (burrs), severe collapse and damage. The tightness of the opening of the box should be appropriate. When taking the flower box, do not peel it off with your fingers to pinch the edge of the lid. The mirror surface, contents and the box inside the box should be adhered firmly, the mirror image should be good, and there should be no scratches or damages on the bottom.
Structure: No protrusions that cause user injury
Impurities (internal): There are no impurities in the bottle that seriously pollute the product. (Hair, insects, etc.).
Impurities (external): No impurities (dust, oil, etc.) that may contaminate the product.
Printing and content: correct, complete and clear, and the script is consistent with the standard sample.
Surface scratches, breakages, etc.: There are no scratches, cracks, dents, etc. on the surface.
Structure and configuration: functionality. The parts cooperate well.
Critical dimensions: within limits
Printing adhesion: 3M-810 tape, pull hard at 45°-90°, and there is no obvious separation of the text part.
Weight: within the limit range ± 2%
Color, appearance, material: in line with standard samples.
