1、结合膜的抗李杰度1. Tensile strength of composite membrane如果结合膜抗刘天度过低,始终无法注意双层线路结合原料的标准,目力必不能够 更好地减少化,,那么在迫降全进程中会造破袋情況。除此本身,结合抽真空内塑料包装袋在常温享制袋If the tensile strength of the composite membrane is too low to consider the provisions of double-layer composite materials, and the eyesight cannot be dispersed as soon as possible, then the bag will be broken during the whole landing process. In addition, composite vacuum packaging bags are made at high temperature里,因一系黏合剂耐低温性差,通常是在一系纷繁结构中,在温度高烹煮中,也会容易造成密封胶性边龟裂、分手后pe热收缩膜脱层状况发生In, because some adhesives have poor temperature resistance, especially in some complex structures, during high-temperature cooking, it will also cause sealing edge cracking and composite membrane delamination2、在生产包裝袋处理工艺流程层级2. On the processing technology level of making packaging bags做礼品盒华气温过高,导致的执封原料特征缩减,导致破袋,做礼品盒袋操作经济压力过大,执封外的执封原料被格压,抽真空性外的执封原料缩减,礼品盒袋流下时礼品盒贷The temperature of the packaging material is too high, resulting in the reduction of the characteristics of the sealing material, leading to the breakage of the bag. The working pressure of the packaging bag is too high, the sealing material outside the sealing is grid pressed, the sealing material outside the sealing property is reduced, and the packaging is damaged when the packaging bag falls型开。袋的执封过度紧张圆润,亦或是有机制生产设备机,会弄坏袋的执封边沿,促使华子捐坏的情況Type open. If the bag is too sharp or there are mechanical equipment, the edge of the bag will be damaged, resulting in the bad condition of huazi donation3、资料层面上3. Material level塑料蒸空包,装贷资料更要有足够的薄厚,薄厚过低,会影响塑料膜的抗压标准不足够,并影响塑料袋碎粉的困局:长度更加重视利用资料中的资料,从各范畴就是缩减利用The composite vacuum bag and packing material must have sufficient thickness. Insufficient thickness will lead to insufficient compressive strength of the composite film and the problem of bag crushing: attach great importance to the materials in the recycled materials, and reduce the recycling in all fields资料,塑造资料过高,结合膜抗压刚度不能,诱发塑料袋粉碎性。在聚乙稀透明膜的加工创造全整个过程中,生成LLDPE和mPE以提高自己高电压聚乙稀的抗压刚度和柔软度,从而降低破袋,比如在较高湿冷冻箱库自然而然是工作生态中技术应用的内包装箱一定是抗寒的内包装箱资料,才是可以加工创造结合膜,否则会诱发 结合膜在较高湿冷冻箱库自然而然是工作生态中脆裂There are too many materials and reconstituted materials, and the compressive strength of the composite membrane is not enough, resulting in the crushing of the bag. In the whole production process of polyethylene film, LLDPE and MPE are added to improve the compressive strength and flexibility of high-pressure polyethylene, so as to reduce bag breakage. If the packaging used in the ultra-low temperature refrigerated natural environment must be cold resistant packaging materials, the composite film can be produced and manufactured, otherwise the composite film will be brittle in the ultra-low temperature refrigerated natural environment4、任何层面上4. Other levels编织袋箱一个重货物或颗粒状类,如盐、洗洁剂等,添充这种小东西后,热封时需排出到来袋内固体,才能减少编织袋箱袋的壁力,再次对固态硬盘安装化学式材料较低力,较低袋的影响。Pack some heavy or powdered items, such as salt, detergent, etc. after filling these items, the gas in the bag should be discharged before heat sealing, so as to reduce the wall force of the packaging bag, release the force of solid chemicals immediately, and reduce the damage of the bag.5,热封层材质的类种,板材厚度及其安全性能对热封刚度有来决定义的引响。5. The type, thickness and quality of heat seal materials have a decisive impact on the heat seal strength.一般来说的组合包装方式惯用的热封装修的材料有CPE、CPPEVA、具有热熔胶相应以外的别的点铝离子型树脂的材料共挤或共混改良薄膜和珍珠棉。热封层装修的材料的板厚一般来说的在20~80um之前,特别情况报告下总有Commonly used heat sealing materials for composite packaging include CPE, cppeva, hot melt adhesive and some other ionic resin coextrusion or blending modified films. The thickness of the heat sealing layer material is generally between 20 and 80um, and there are also special cases达100~200um的,同本身执封涂料,其执封挠度随执封度度的增高而增高,蒸者袋的执封挠度普通条件达40~50牛顿,如此,其执封涂料度度应在60~80um上述。6、热封温度因素对热封挠度的后果十分直观。For the same sealing material up to 100~200um, its sealing strength increases with the increase of sealing degree. The sealing strength of steamer bag is generally required to reach 40~50 Newton. Therefore, the sealing material degree should be above 60~80um. 6. The influence of heat sealing temperature on heat sealing strength is relatively direct.各个资料的熔融平均气温的的高低,随时直接决定分手后软型袋的zui低热封平均气温。生產方式中,由热封水压,制袋线速度各类分手后软型材料的它的厚度等供需双领域干扰,实计运用的热封平均气温并不是The melting temperature of various materials directly determines the Zui low heat sealing temperature of composite bags. In the production process, due to the influence of heat sealing pressure, bag making speed and the thickness of composite substrate, the actual heat sealing temperature is often要大于热封食材的熔融温差。热封的压越小,规范热封温差越高;机速越快,组合膜的铺装食材越厚,规范的热封温差也越高。It should be higher than the melting temperature of the heat sealing material. The lower the pressure of heat sealing, the higher the temperature of heat sealing is required; The faster the machine speed is, the thicker the surface material of the composite film is, and the higher the required heat sealing temperature is.热封湿度若低过热封资料的泡软点,则不论什么怎么样加高经济压力或减少热封用时,均不要能使热封层zhen正封合。并且若热封湿度过高,又极容易挫裂伤焊边处的热封资料熔融If the heat sealing temperature is lower than the softening point of the heat sealing material, no matter how to increase the pressure or extend the heat sealing time, it is impossible to make the heat sealing layer Zhen positive sealing. However, if the heat sealing temperature is too high, it is very easy to damage the melting of the heat sealing material at the welding edge抽出,形成“根切”原因,有很大程度的下降密封的热封承载力和包装袋的耐冲洗安全性能。Extrusion produces "undercut" phenomenon, which greatly reduces the heat sealing strength of the seal and the impact resistance of the bag.7、要到达比较好的热封密度,必然的工作压力必不行少。7. To achieve the ideal heat sealing strength, a certain pressure is essential.对干轻簿包装方式袋,热封气压每组要以做到2k/cm22,而现在包覆膜总板厚为的提升而相应的提升。若执封气压缺点,二层pe膜当中得以以做到zhen正地熔合,致合小面积的热For dry, light and thin packaging bags, the heat sealing pressure should reach at least 2k/cm22, which increases with the increase of the total thickness of the composite film. If the sealing pressure is insufficient, it is difficult to achieve positive fusion between the two films, causing local heat封不利,还有得以赶尽夹在惶缝当中的利用气泡,可能会导致虎煜;


Poor sealing, or it is difficult to catch up with the bubbles caught in the middle of the panic seam, resulting in tiger Yu;其实,执封有压力值也不能越大越高,应以不捐伤悍边为宣,这是由于在较高的执封摄氏度时,悍边的执封素材已外干半熔融感觉,有效的的有压力值易格走那部分执封料,使悍缝边绿Of course, the greater the sealing pressure is, the better. It should be declared not to damage the hard edge, because at a higher sealing temperature, the sealing material of the hard edge has been dry and semi molten, and the large pressure changes part of the sealing material to make the hard edge green型成半立即切断阶段,管道焊接发脆,执封比强度减少。Forming a semi cut-off state, the weld is brittle and the sealing strength is reduced.8、热封期限常见由制袋机的效率决定性。8. The heat sealing time is mainly determined by the speed of the bag making machine.热封时候也是干扰悍缝封合抗压强度和外型的同一个关键的的因素。重复的热封湿度和负担,热封时候长,则热封层熔合更有效,联系更粘紧,但热封时候太短,加容易构成悍缝Heat sealing time is also a key factor affecting the sealing strength and appearance of tough seams. With the same heat sealing temperature and pressure, if the heat sealing time is long, the heat sealing layer will be fused more fully and bonded more firmly, but if the heat sealing time is too long, it is easy to cause sharp cracks起褶,影响力油漆颜色。Wrinkle, affecting the appearance.9、热封后的焊接件若加热不大好,往往会应响焊接件的表面铺布度,同时还对热封刚度有千万的应响。9. If the weld after heat sealing is not cooled well, it will not only affect the appearance flatness of the weld, but also have a certain impact on the heat sealing strength.一系列冷去全期间只是 用在务必的压强下,用较低的工作温度对马上熔融热封后的焊接去定形,除掉剪切力收集的全期间。但是,压强没有,一系列冷去水嵌套循环往复不畅,嵌套循环往复量没有,水的温度太高,或一系列冷去不适时总要造成一系列冷去恶意,热包边起翘,执封抗拉强度大大减少。The cooling process is a process of eliminating stress concentration by shaping the weld just after melting and heat sealing with a lower temperature under a certain pressure. Therefore, insufficient pressure, poor cooling water circulation, insufficient circulation volume, too high water temperature, or untimely cooling will lead to poor cooling, warping of hot sealing edges, and reduced sealing strength.
