速凍食品包裝生產(chǎn)中要注意什么!

來源:http://m.wujikeji.com/ 日期:2023-02-02

袋子的耐沖擊性能差,運(yùn)輸、裝卸、貨架擺放過程中容易受到外來力的破壞,極易出現(xiàn)破袋、開袋現(xiàn)象,不但影響包裝產(chǎn)品的外觀,同時(shí)也不能起到包裝本身應(yīng)有的作用;
The impact resistance of the bag is poor, and it is easy to be damaged by external forces during transportation, loading and unloading, and shelf placement. It is easy to break the bag and open the bag, which not only affects the appearance of the packaged product, but also cannot play the role of the packaging itself;
包裝袋本身的爽滑性不好,生產(chǎn)過程中表現(xiàn)為開口性較差,生產(chǎn)效率低,同時(shí)也會(huì)使包裝袋的使用率降低,對(duì)成本造成浪費(fèi);
The smoothness of the packaging bag itself is not good, and the opening is poor in the production process, and the production efficiency is low. At the same time, the use rate of the packaging bag will be reduced, and the cost will be wasted;
包裝袋的熱封強(qiáng)度不夠、熱封溫度過高造成熱封層的損害現(xiàn)象,造成包裝袋的保護(hù)性能降低,內(nèi)容物的保質(zhì)期大大縮短,使內(nèi)容物達(dá)不到相應(yīng)的保質(zhì)期;
The insufficient heat sealing strength and high heat sealing temperature of the packaging bag cause the damage of the heat sealing layer, resulting in the reduction of the protective performance of the packaging bag, and the greatly shortened shelf life of the contents, so that the contents can not reach the corresponding shelf life;
包裝袋層間剝離強(qiáng)度小、拉斷力不夠,包裝袋的力學(xué)性能較差,造成包裝袋分層、包裝袋不能夠達(dá)到應(yīng)有的承重作用,對(duì)內(nèi)容物不能起到有效的保護(hù)作用;
The peeling strength between layers of packaging bags is small, the breaking force is not enough, and the mechanical properties of packaging bags are poor, resulting in the layering of packaging bags, the packaging bags can not achieve their due load-bearing function, and the content can not play an effective protection role;
速凍食品的耐寒性達(dá)不到要求,在溫度較低的情況下,不能保持材料原有的性能,包裝材料較脆,使包裝材料力學(xué)強(qiáng)度下降,造成包裝袋破裂及開裂,更不能滿足對(duì)內(nèi)容物的保護(hù)作用;、
 濟(jì)南訂做食品包裝袋
The cold resistance of quick-frozen food can not meet the requirements. Under the condition of low temperature, it can not maintain the original performance of the material. The packaging material is brittle, which reduces the mechanical strength of the packaging material, causes the packaging bag to crack and crack, and can not meet the protection function of the content;
包裝袋易撕口的作用不能有效發(fā)揮,撕裂強(qiáng)度太大造成包裝袋不易開口,撕裂強(qiáng)度太小造成包裝袋力學(xué)性能降低,所以既要滿足包裝袋易撕口的人性化設(shè)計(jì),同時(shí)也要完成產(chǎn)品的保護(hù)作用;
The function of the easy-to-tear mouth of the packaging bag cannot be effectively played. Too large tear strength makes the packaging bag difficult to open, and too small tear strength reduces the mechanical properties of the packaging bag. Therefore, it is necessary to meet the humanized design of the easy-to-tear mouth of the packaging bag, and also to complete the protection of the product;
包裝袋的穿刺性能,速凍食品冷凍后一般比較堅(jiān)硬,特別是魚、肉制品,含有骨頭及硬質(zhì)物體,運(yùn)輸及堆放中產(chǎn)品擠壓很容易使包裝袋穿破,使包裝袋密封性造成破壞,因此速凍食品對(duì)包裝袋的穿刺性要求很高。
The puncture performance of the packaging bag is generally relatively hard after freezing, especially for fish and meat products, which contain bones and hard objects. It is easy to break the packaging bag and damage the sealing of the packaging bag when the products are squeezed during transportation and stacking. Therefore, the puncture performance of the packaging bag for quick-frozen food is very high.
