济南同乐城tlc126经常出现破袋的现象怎么办?
发布于:2017/01/05   高温真空袋由于其重量轻、体积小、导热快,灭菌时间短,可以更好地保持颜色和香味的内容,所以逐渐取代锡和玻璃罐的一部分,但由于包装材料的许多属性是影响袋,消毒等过程,这是一个潜在的袋子破损的风险。
  Because of its light weight, small volume, fast heat conduction and short sterilization time, the high temperature vacuum bag can better maintain the content of color and fragrance, so it gradually replaces a part of tin and glass can. However, because many properties of packaging materials affect the bag, sterilization and other processes, it is a potential risk of bag damage.
  原因a:基材问题
  Cause a: substrate problem
  烹饪袋与产品一起加热,这就决定了烹饪袋的表面材料在烹饪后具有很好的稳定性,尤其是在烹饪和冷却后大小的稳定性。如果基材的热稳定性不好,煮熟冷却后容易破袋。
  The cooking bag is heated together with the product, which determines that the surface material of the cooking bag has good stability after cooking, especially after cooking and cooling. If the thermal stability of the substrate is not good, it is easy to break the bag after cooking and cooling.
  对策:
  Countermeasures:
  烹饪真空袋常用的是耐高温更好的宠物,纽约,,RCPP,如基材,应注意各种基材保质期,尤其应注意RCPP的保质期,因为RCPP衬里材料的高温烹饪,起着核心作用在蒸煮袋的性能,如果RCPP质量差或有保质期,烹饪时冷却后压很大程度上有脆性断裂的现象。
  The cooking vacuum bag is commonly used for pets with better high temperature resistance, New York, rcpp, such as base materials, should pay attention to the shelf life of various base materials, especially the shelf life of rcpp, because the high temperature cooking of rcpp lining materials plays a key role in the performance of cooking bag. If the quality of rcpp is poor or there is shelf life, the pressure after cooling during cooking has the phenomenon of brittle fracture to a large extent.

  原因二:制袋技术的影响
  Reason 2: the influence of bag making technology
  封袋刀的温度、压力和速度是制袋过程中的三个主要因素。热封是热与力相互作用的结果。一方面,在熔融状态下的密封面上,大分子相互扩散、渗透、缠绕,达到密封的密闭性;另一方面,聚合物分子在熔融状态下借助热封工具的压力,使两层膜熔为一体,冷却后保持一定的强度。
  The temperature, pressure and speed of the bag sealing knife are the three main factors in the bag making process. Heat sealing is the result of the interaction of heat and force. On the one hand, on the sealing surface in the melting state, macromolecules diffuse, permeate and wind each other to achieve the sealing tightness; on the other hand, polymer molecules melt the two layers of film into one with the help of the pressure of the heat sealing tool in the melting state, and maintain a certain strength after cooling.
  对策:
  Countermeasures:
  由于高需求的使用环境中,通常需要蒸煮袋热封强度强,这就需要蒸煮袋的组合结构合理,衬里材料设置温度和压力,使袋,尤其必须注意填补和袋体底部结,因为烹饪条件下,材料收缩,水分的交接将成为焦点,热空气的攻击。热封次数的多少在很大程度上影响热封强度,合理设置制袋时的横封数和竖封数可以保证封边具有良好的热封强度。
  Due to the high demand of the use environment, the cooking bag usually needs strong heat sealing strength, which requires the reasonable combination structure of the cooking bag, the temperature and pressure of the lining material to make the bag, especially the filling and the bottom knot of the bag, because under the cooking conditions, the material shrinkage, the water handover will become the focus, and the hot air attack. The number of times of heat sealing affects the heat sealing strength to a great extent. Setting the number of horizontal and vertical seals reasonably can ensure that the edge has good heat sealing strength.
  同时,应注意冷却后的热封,在一定的压力下冷却,用较低的温度将热封的位置刚好熔掉,以定型的过程消除应力集中。因此,对于制袋过程,尤其是制作烹饪袋时,要特别注意温度、压力、机器速度的合理分配,以保证烹饪袋在后续的加工过程中不会破袋。
  At the same time, attention should be paid to the heat seal after cooling, cooling under a certain pressure, using a lower temperature to melt the position of the heat seal just to eliminate the stress concentration during the setting process. Therefore, for the bag making process, especially when making cooking bags, pay special attention to the reasonable distribution of temperature, pressure and machine speed to ensure that the cooking bags will not break in the subsequent processing.
