General color box related to the material can be divided into 2 categories: face paper, pit paper.
Usually box box paper is commonly used (in Taiwan): gray copper, white copper, single copper, gorgeous cards, gold cards, platinum cards, silver cards, laser cards and so on.
There are two kinds of whiteboards: white copper, copper, and copper.
What they have in common is that both sides are white.
The difference is "nickel bronze": one side is smooth and not smooth, that is, one side has a coated surface and one side has no coated surface. The popular point is that the front can be printed and the reverse can not be printed.
"Single Copper": Both sides have a coated surface on both sides, and both sides can be printed.
The grey board has this kind of paper, but it is not used for color box, gray board, it is the so-called "grey copper paper" that is the front is white, can be printed, the opposite is gray, can not be printed.
The general white card is the "white board" paper, but it is only the general quotation, except for special white cards, such as platinum cards and silver cards.
About the detection of packaging materials
Packaging material standard
Packaging material name: color box
1. range
This standard specifies the quality and technical requirements, test methods, and transportation and storage requirements of the packaging box.
This standard applies to all packaging color box materials used by the company.
2. Reference Standard
GB11680 Paper Packaging Sanitary Standard
3. Inspection standards
3.1 Quality Hygiene Requirements
3.1.1 appearance requirements
The surface is clean and smooth, with no wrinkles and no impurities. Fonts and patterns should be clear and correct. There should be no misprints, missing prints, and no ink contamination.
3.1.2 Process Requirements
A size meets the specifications, deviation is within the allowable range, and the color box that needs to install pit paper should be tested and qualified.
b The bonding of the color box should be tight and firm, without loosening and cracking.
c The color box material and structure are the same as the pattern or drawings.
3.1.3 Sanitation requirements
Should comply with the provisions of GB11680.
3.2 Detection methods and defect classification
3.2.1 Appearance detection
Visually in a bright room.
3.2.2 Process Requirements Inspection
Compare process files and data, visually in a bright room or using a measurement tool.
3.2.3 Health Inspection
Check the supplier's hygiene license, official inspection report, and the certificate of each batch of product.
3.2.4 Defects are classified as minor defects, major defects, or severe defects, as specified in Table 1.

4. Sampling criteria
Each batch of external packaging carton incoming materials was randomly sampled according to MIL-STD-105E LEVEL 2, AQL: CR = 0MAJ = 1.0 MIN = 2.5.
If the inspection fails, double sampling is repeated. Retest failed, the batch of raw materials refused.
5. Transport and storage
5.1 Transportation
Transport vehicles must be clean and clean. Do not mix with harmful, toxic, odorous and other easily contaminated items.
5.2 Storage
Store in a dry, cool, ventilated, clean warehouse. Warehouses should have moisture-proof facilities. No rat, no pests and other pollution. Keep a proper distance from the wall and ceiling when storing;
