塑料袋缝合强度的要求

Requirements for stitching strength of plastic bags

济南塑料袋在制作时如果是选用新旧质料配混时，要特别注意混合的均匀性，而在缝合的时分，关于强度也是有严格要求。无强度要求的编织袋上口锁边一周，针距可密，线可细。关于济南塑料袋主体衔接部的抗拉强度，要求有需要到达基本强度的67%以上，底部衔接部的抗拉强度有需要到达基本强度的42%以上。

When making plastic bags in Jinan, if new and old materials are used for mixing, special attention should be paid to the uniformity of the mixing, and there are strict requirements for strength during stitching. The upper edge of the woven bag without strength requirements is locked for one week, and the needle spacing can be dense and the thread can be fine. Regarding the tensile strength of the main connection part of Jinan plastic bags, it is required to reach over 67% of the basic strength, and the tensile strength of the bottom connection part needs to reach over 42% of the basic strength.

其实影响塑料袋缝合强度的主要因素包含缝合线的品种和类型，针距巨细，线迹，卷边或者边缝合线到袋边的尺度，热切和冷切方法等。

In fact, the main factors that affect the stitching strength of plastic bags include the variety and type of stitching thread, needle pitch, stitching, the scale of the curled or edge stitching thread to the bag edge, hot and cold cutting methods, and so on.

塑料袋老化的预防措施

Preventive measures for aging of plastic bags

1.塑料袋在自然环境下即在阳光直射的条件下，一周后其强度下降25%，两周后会下降40%，基本上已不能运用。也就是说塑料袋的贮存保管问题非常重要。

1. In natural environments, such as direct sunlight, the strength of plastic bags decreases by 25% after one week and by 40% after two weeks, making them basically unusable. That is to say, the storage and storage of plastic bags are very important.

2.在塑料包装水泥后放在露天环境受阳光直射，强度会急剧下降。

2. After plastic packaging of cement, placing it in an open environment under direct sunlight will cause a sharp decrease in strength.

3.塑料袋贮运过程中温度过高(集装箱运送)或遇到雨淋,都会导致其强度下降，然后达不到维护内装物品的质量要求。

3. During the storage and transportation process of plastic bags, if the temperature is too high (transported in containers) or if they encounter rain, their strength will decrease, and they will not meet the quality requirements for maintaining the contents.

4.再产生料的过多参加也是加强塑料袋老化的原因之一。

Excessive participation in the production of raw materials is also one of the reasons for strengthening the aging of plastic bags.
