During the production of gift box packaging, there are many operational steps, and the control of each step is crucial to the production of the box. The quality of the process control determines the quality of the product.
In the manufacturing process, every operation hides quality risks. These risks are not due to imperfect process design or incomplete equipment performance; most of them result from the lack of quality awareness and uneven skill levels of the operators. Coupled with lax process control, quality defects often occur, posing the greatest challenge to the stability of gift box packaging quality. Improving the quality awareness of managers and operators is particularly important and is the most effective way to prevent defects.
The most common defects or quality control points include:
1, Loose Edges: After pasting the paper, there is insufficient adhesion at the four edges of the box body, and there may be a gap between the paper and the gray board.
2, Wrinkles: Irregular and uneven folds appear on the surface of the paper after pasting, with varying lengths.
3, Corner Breakage: Paper damage and white spots appear at the four corners of the box after pasting.
4, Gray Exposure (Bottom Exposure): Due to the inaccuracy of die-cutting or misalignment during pasting, the pasted paper may shift after folding, causing the gray board to be exposed.
5, Bubbles: Irregular and varying-sized bubbles appear on the surface of the box.
6, Glue Stains: Residual traces of glue on the surface.
7, Protrusions (Dark Spots): Granular residues in the lower layer of the material cause localized bulges on the surface, affecting the smoothness of the box.
8, High-Low Edges: After semi-die-cutting or grooving the gray board, inconsistent heights may occur on adjacent edges when folding.
9, Water Ripples: After pasting the box, to ensure tight adhesion at the edges, scraping the edges of the box with a scraper is necessary. Improper force application can result in uneven, irregular strips or small bubbles, resembling water ripples.
