方底袋过程中容易出现的问题及解决措施

发布日期:2022-07-30 作者:www.jnsuliao.com 点击:

方底袋的制作包装袋品质及热封品质,对方底袋包装全过程、运送、内容物的存储及商品分销商等重要环节都是有非常大危害。那么方底袋在热封过程中容易出现哪些问题呢?
The production of square bottom bags, the quality of packaging bags and heat sealing quality, the whole process of packaging, transportation, storage of contents, commodity distributors and other important links are all very harmful. So what problems are prone to occur in the heat sealing process of square bottom bags?
1、方底袋不好导致内容物霉变该怎么办?
1. What should I do if the contents are moldy due to the bad square bottom bag?
问题:
Question:
塑料薄膜的抗污热封性欠佳,主要是内透层所应用的环氧树脂不适合。
The anti fouling heat sealing property of plastic film is poor, mainly because the epoxy resin used in the inner permeable layer is not suitable.
解决措施:
Solutions:
选用抗污热封性好的塑料薄膜。
Choose plastic film with good dirt resistance and heat sealing.
一般来说,LDPE具备中等水平的抗污热封性,EVA在VA成分很大时具备优良的抗污热封性,LDPE也具备优良的抗污热封性,无机化合物环氧树脂和茂金属高聚物则具备的抗污热封性。
Generally speaking, LDPE has a medium level of antifouling heat sealing property, EVA has excellent antifouling heat sealing property when VA composition is large, LDPE also has excellent antifouling heat sealing property, and inorganic compound epoxy resin and metallocene polymer have antifouling heat sealing property.
2、济南方底袋密封变脆及脆性断裂该怎么办?
2. How should Jinan square bottom bag seal become brittle and brittle fracture?
(1)热封温度过高。
(1) The heat seal temperature is too high.
(2)工作压力过大。
(2) Working pressure is too high.
(3)热封时间太长。
(3) The heat sealing time is too long.
(4)上端密封器的边沿过度锐利或所包覆的聚四氟乙烯毁坏。
(4) The edge of the upper seal is too sharp or the PTFE covered is damaged.
(5)底端密封的硅胶扎实。
(5) The silicone sealed at the bottom is solid.

(6)在复合型和熟成全过程中,一部分黏合剂渗透到塑料薄膜内部。板材因为遭受黏合剂的渗入危害,延展性(抗撞击力)有一定的降低,延性提升。
(6) In the whole process of compounding and ripening, part of the adhesive penetrates into the plastic film. Due to the penetration of adhesives, the ductility (impact resistance) of plates has been reduced to a certain extent, and the ductility has been improved.
(7)方底袋复合包装制冷和置放后,热密封抗压强度有一定的提高,另外也发生变化脆的趋于。
(7) After the composite packaging with square bottom bags is refrigerated and placed, the compressive strength of heat sealing is improved to a certain extent, and in addition, it also changes and tends to be brittle.
(1)据内透层方底袋原材料的热封特点,挑选适合的生产加工温度,工作压力和热封时间。
(1) According to the heat sealing characteristics of the raw materials of the inner permeable square bottom bag, the suitable production and processing temperature, working pressure and heat sealing time are selected.
(2)改进上端热封刀表层情况,使密封器表层整平。
(2) Improve the surface condition of the upper heat sealing knife to level the surface of the sealer.
(3)以聚四氟乙烯布包覆完好无损。
(3) The PTFE cloth is intact.
(4)挑选适合强度的硅胶垫。
(4) Choose a silicone pad with suitable strength.
