针对大米包装行业，爆袋是生产商和经销商最头疼的损耗问题。这篇内容通过材质分析、结构优化及物流防护三个维度，为您的大米包装客户提供深度解决方案。

In the process of grain and oil circulation, rice bags are often faced with high drop, gravity stacking and rice grain tip puncture test. Once there is a "burst bag" or "leakage", not only lead to oxidation and deterioration of rice, but also seriously affect the image of the brand in the minds of supermarkets and consumers.

Rice packaging how to do "hundred falls do not break"?旭鼎新材料包装为您总结了降低爆袋率的三大材质核心策略。

I. Core material: why nylon (PA) is a must?

Many rice packaging in order to reduce costs, the use of single-layer PE or simple PET / PE structure, which is the main cause of bag burst.

• Nylon (PA) is irreplaceable: The molecular structure of nylon is extremely tough and tensile. It is like the "bulletproof vest" in a bag, effectively absorbing the impact of a fall.
• 抗穿刺性能： When rice (especially long grain rice) is vacuumed, the tips of the grains become extremely sharp. The nylon layer prevents these "little needles" from piercing the bag wall.
• 推荐结构： * 高档大米（真空）：PA/PE（双层复合）或 PET/PA/PE（三层复合）。
  • Heavy duty rice (5kg-10kg): 必须增加尼龙厚度，确保复合强度。

Thickness and Heat Seal: The "Golden Ratio" at the sealing point

数据显示，80%的爆袋发生在热封边或corner of R。

• 厚度控制： 针对不同规格，厚度有讲究。
  • 2.5kg pack: 100-120μm recommended for one side.
  • 5kg pack: 140-160μm recommended for one side.
• 热封强度： Xuding adopts imported modified PE as the heat sealing layer, which has a wider heat sealing window. This means that during high-speed bag making, the sealing area can realize complete molecular fusion, avoiding the cracking caused by "false sealing".
• 防爆筋设计： 在大规格风琴袋（侧折边袋）的设计中，我们会优化封口模具，减少四层折叠处的应力集中。

III. Physical design optimization: Reducing "hard knocks"

除了材质，袋型的细节设计也能显著提升抗跌落能力：

1. 圆角设计： Compared to right angles, rounded corners (R-angles) can effectively disperse the instantaneous pressure during a fall and reduce breakage at sharp corners.
2. 排气孔工艺： 对于非真空的大米袋，科学的针孔排气设计能排出多余空气，防止堆码时气压过大撑破袋体。
3. 适配性测试： 旭鼎新材料提供模拟物流测试，包括跌落测试（1.2米高度自由落体）和振动测试，确保每一批大米袋都能经受长途跋涉。

💡 旭鼎专家的采购贴士：

Don't just focus on the "unit price". If 10,000 bags are 500 dollars cheaper, but 50 more bags of rice explode during transportation, the loss of payment and brand reputation far exceeds the money saved on packaging materials.

建议： * 测拉力： 收到货后用力撕扯封口，应是膜材断裂而非封口脱开。

• 测真空： 抽真空24小时后观察是否返气。
