手提袋爆裂常见原因分析

2、材料因素：纸张耐折度低；膜的质量不好；压痕刀板压痕条问题。
2. Material factors: low folding resistance of paper; poor quality of film; indentation strip of indentation cutter board.
非覆膜类产品风险提示：手提袋覆膜与不覆膜，其制作时对纸张的耐折要求存在很大差异性。单面涂布白卡纸有着更好的挺度，在制作非覆膜类产品时，必须评估工艺环境及爆裂风险，建议全工序打样确认使用效果。并在大货生产时严格参照打样参数。
Risk hints of non-coated products: there is a great difference between the handbag coated and non-coated products in the requirement of paper folding resistance. Single-side coated white cardboard has better stiffness. When making non-coated products, it is necessary to assess the process environment and burst risk, and it is recommended that the whole process proofing confirm the use effect.
