What is 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 and printing quality inspection mainly include the abrasion resistance of printing ink layer (anti-scratch performance), ink adhesion fastness and color discrimination detection. During the inspection process, the packaging products do not appear ink loss, deinking and other phenomena. Qualified product. There are also different inspection standards and methods for different cosmetic packaging. Let's take a look at the inspection methods and standards of various types of packaging.
First, make sure that the materials used must be hygienic and non-toxic:
All materials should have certain chemical stability, cannot interact with the products they contain, and are not prone to discoloration and fading when exposed to light. New products are developed and packaged with green and environmentally friendly materials, and the compatibility with the material body is tested at high and low temperature to ensure that the material body will not deteriorate, delaminate, change color and thin; for example: mask cloth, air cushion sponge, bottles with special gradient process, etc.
Second, the inspection standards of different packaging:
1. Inner plug
Structure: No protrusions that could cause injury to users, no misalignment of threads, and flat bottom.
Impurities (internal): There are no impurities in the bottle that would seriously contaminate the product. (hair, insects, etc.).
Impurities (external): No impurities (dust, oil, etc.) that may contaminate the product.
Printing and content: correct, complete and clear, the script is consistent with the standard sample.
Air bubbles: no obvious air bubbles, ≤3 air bubbles within 0.5mm in diameter.
Structure and assembly: functional, cooperates well with the cover and other components, the gap is less than or equal to 1mm, and there is no leakage.
Size: ±2mm within limits
Weight: ±2% within the limit
Color, appearance, material: conform to the standard.
2. Plastic bottles
The bottle body should be stable, the surface is smooth, the thickness of the bottle wall is basically uniform, there is no obvious scar, deformation, and there should be no cold explosion and crack. The mouth of the bottle should be straight and smooth, without burrs (burrs), and the matching structure of the thread and bayonet should be intact and correct. The cooperation between the bottle and the cap should be tight, there is no slippage, looseness, and no leakage. The inside and outside of the bottle should be clean.
Construction: No protrusions that could cause injury to the user
Impurities (internal): There are no impurities in the bottle that would seriously contaminate the product. (hair, insects, etc.).
Impurities (external): No impurities (dust, oil, etc.) that may contaminate the product.
Printing and content: correct, complete and clear, the script is consistent with the standard sample.
Surface scratches, damage, etc.: The surface is free of scratches, cracks, dents, etc.
Structure and assembly: functionality. Works well with various components such as the inner plug/cap.
Critical dimensions: ±2mm within limits
Printing adhesion: 3M-810 tape, pull hard at 45°-90°, and the text part has no obvious separation.
Weight: ±2% within the limit
Color, appearance, material: conform to the standard.
3. Cosmetic tube
Construction: No protrusions that could cause injury to the user
Impurities (internal): There are no impurities in the bottle that would seriously contaminate the product. (hair, insects, etc.).
Impurities (external): No impurities (dust, oil, etc.) that may contaminate the product.
Printing and content: correct, complete and clear, the script is consistent with the standard sample.
Surface scratches, damage, etc.: The surface is free of scratches, cracks, dents, etc.
Structure and assembly: functionality. All parts fit well.
Critical Dimensions: Within Limits
Printing adhesion: 3M-810 tape, pull hard at 45°-90°, and the text part has no obvious separation.
Weight: ±2% within the limit
Color, appearance, material: conform to the standard.
4. Private label
Printing and content: The text is correct, complete and clear, and the manuscript conforms to the standard.
Document color: conform to the standard.
Surface scratches, damages, etc.: No scratches, cracks, tears, etc. on the surface.
Impurities: No visible impurities (dust, oil, etc.)
Color, appearance, material: conform to the standard.
5.Cosmetic packaging case (powder compact, eye shadow palette, etc.)
The surface of the box should be smooth and correct, and there should be no obvious scratches, burrs (burrs), serious collapse and damage. The opening tightness of the box should be appropriate. When taking out the flower box, do not force it with fingers to hold the edge of the cover, and the bottom does not fall off by itself. The mirror surface, contents and the box in the box should be firmly attached, the mirror surface should have a good image, and there should be no scratches and damages on the bottom.
Construction: No protrusions that could cause injury to the user
Impurities (internal): There are no impurities in the bottle that would seriously contaminate the product. (hair, insects, etc.).
Impurities (external): No impurities (dust, oil, etc.) that may contaminate the product.
Printing and content: correct, complete and clear, the script is consistent with the standard sample.
Surface scratches, damage, etc.: The surface is free of scratches, cracks, dents, etc.
Structure and assembly: functionality. All parts fit well.
Critical Dimensions: Within Limits
Printing adhesion: 3M-810 tape, pull hard at 45°-90°, and the text part has no obvious separation.
Weight: ±2% within the limit
Color, appearance, material: conform to the standard.
