      濟南塑料袋經常出現破袋的現象怎么辦?
      發布于:2021/02/01 高溫真空袋由于其重量輕、體積小、導熱快,滅菌時間短,可以更好地保持顏色和香味的內容,所以逐漸取代錫和玻璃罐的一部分,但由于包裝材料的許多屬性是影響袋,消毒等過程,這是一個潛在的袋子破損的風險。
        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:基材問題
        Cause a: substrate problem
        烹飪袋與產品一起加熱,這就決定了烹飪袋的表面材料在烹飪后具有很好的穩定性,尤其是在烹飪和冷卻后大小的穩定性。如果基材的熱穩定性不好,煮熟冷卻后容易破袋。
        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.

        烹飪真空袋常用的是耐高溫更好的寵物,紐約,,RCPP,如基材,應注意各種基材保質期,尤其應注意RCPP的保質期,因為RCPP襯里材料的高溫烹飪,起著核心作用在蒸煮袋的性能,如果RCPP質量差或有保質期,烹飪時冷卻后壓很大程度上有脆性斷裂的現象。
        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:制袋技術的影響
        Reason 2: the influence of bag making technology
        封袋刀的溫度、壓力和速度是制袋過程中的三個主要因素。熱封是熱與力相互作用的結果。一方面,在熔融狀態下的密封面上,大分子相互擴散、滲透、纏繞,達到密封的密閉性;另一方面,聚合物分子在熔融狀態下借助熱封工具的壓力,使兩層膜熔為一體,冷卻后保持一定的強度。
        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.
        對策:
        Countermeasures:
        由于高需求的使用環境中,通常需要蒸煮袋熱封強度強,這就需要蒸煮袋的組合結構合理,襯里材料設置溫度和壓力,使袋,尤其必須注意填補和袋體底部結,因為烹飪條件下,材料收縮,水分的交接將成為焦點,熱空氣的攻擊。熱封次數的多少在很大程度上影響熱封強度,合理設置制袋時的橫封數和豎封數可以保證封邊具有良好的熱封強度。
        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.
        同時,應注意冷卻后的熱封,在一定的壓力下冷卻,用較低的溫度將熱封的位置剛好熔掉,以定型的過程消除應力集中。因此,對于制袋過程,尤其是制作烹飪袋時,要特別注意溫度、壓力、機器速度的合理分配,以保證烹飪袋在后續的加工過程中不會破袋。
        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.
