食品包裝袋定制如何正確選擇?

來(lái)源:http://lusp7.com/ 日期:2024-02-21

標(biāo)準(zhǔn)一:食品級(jí)原材料

Standard 1: Food grade raw materials

塑料包裝袋必須要達(dá)到食品級(jí),因?yàn)橹苯优c食品接觸,如果原材料不過(guò)關(guān),用了回收料或者工業(yè)級(jí)的材料,雖然在外觀上看不出區(qū)別,但是對(duì)食品會(huì)產(chǎn)生很大的影響,甚對(duì)人體造成一定的危害。

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.

標(biāo)準(zhǔn)二:耐寒性

Standard 2: Cold resistance

冷凍食品通常在零下的環(huán)境中存儲(chǔ),很多情況下需要急速降溫,在這個(gè)情況下,包裝材料的力學(xué)強(qiáng)度會(huì)隨之下降,使袋子很容易碎。因此,耐寒性是冷凍食品包裝袋定制時(shí)特別需要特別注意的。

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.

標(biāo)準(zhǔn)三:耐沖擊性

Standard 3: Impact resistance

為防止在運(yùn)輸、裝卸的過(guò)程中受到外力的破壞,對(duì)袋子的耐沖擊性也有較高的要求。

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

標(biāo)準(zhǔn)四:熱封強(qiáng)度

Standard 4: Heat sealing strength

袋子的熱封強(qiáng)度不夠或者熱封溫度過(guò)高,都會(huì)導(dǎo)致封口不好。

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

標(biāo)準(zhǔn)五:拉斷力、層間剝離強(qiáng)度

Standard 5: Breaking force and interlayer peel strength

包裝袋的力學(xué)性能如果比較差,很容易導(dǎo)致分層、無(wú)法達(dá)到應(yīng)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.

標(biāo)準(zhǔn)六:耐穿刺性

Standard 6: puncture resistance

冷凍后的食品一般比較堅(jiān)硬,運(yùn)輸及堆放過(guò)程中很容易將包裝袋穿破,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.

標(biāo)準(zhǔn)七:抗壓性

Standard 7: Compression resistance

這一點(diǎn)主要針對(duì)在運(yùn)輸和搬運(yùn)過(guò)程中的跌落或者沖擊等對(duì)產(chǎn)品的損害。

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