食品包装袋定制如何正确选择？

来源：http://www.scuhtg.com/ 日期：2024-02-21

标准一：食品级原材料

Standard 1: Food grade raw materials

塑料包装袋必须要达到食品级，因为直接与食品接触，如果原材料不过关，用了回收料或者工业级的材料，虽然在外观上看不出区别，但是对食品会产生很大的影响，甚对人体造成一定的危害。

Plastic packaging bags must reach food grade because if they come into direct contact with food, if raw materials are not up to standard and recycled or industrial grade materials are used, although there may not be a noticeable difference in appearance, it can have a significant impact on food safety and even pose a certain risk to human health.

标准二：耐寒性

Standard 2: Cold resistance

冷冻食品通常在零下的环境中存储，很多情况下需要急速降温，在这个情况下，包装材料的力学强度会随之下降，使袋子很容易碎。因此，耐寒性是冷冻食品包装袋定制时特别需要特别注意的。

Frozen food is usually stored in a sub zero environment, and in many cases, rapid cooling is required. In this case, the mechanical strength of packaging materials will decrease, making the bags easy to break. Therefore, cold resistance is particularly important when customizing frozen food packaging bags.

标准三：耐冲击性

Standard 3: Impact resistance

为防止在运输、装卸的过程中受到外力的破坏，对袋子的耐冲击性也有较高的要求。

To prevent damage from external forces during transportation and loading and unloading, there are also high requirements for the impact resistance of bags.

标准四：热封强度

Standard 4: Heat sealing strength

袋子的热封强度不够或者热封温度过高，都会导致封口不好。

Insufficient heat sealing strength or high heat sealing temperature of the bag can lead to poor sealing.

标准五：拉断力、层间剥离强度

Standard 5: Breaking force and interlayer peel strength

包装袋的力学性能如果比较差，很容易导致分层、无法达到应有的承重作用。

If the mechanical properties of packaging bags are relatively poor, it is easy to cause layering and fail to achieve the expected load-bearing effect.

标准六：耐穿刺性

Standard 6: puncture resistance

冷冻后的食品一般比较坚硬，运输及堆放过程中很容易将包装袋穿破，因此冷袋子的耐穿刺性要求很高。

Frozen food is generally relatively hard, and it is easy to break through the packaging bags during transportation and stacking, so the puncture resistance of cold bags is required to be high.

标准七：抗压性

Standard 7: Compression resistance

这一点主要针对在运输和搬运过程中的跌落或者冲击等对产品的损害。

This mainly focuses on the damage to the product caused by falls or impacts during transportation and handling.
