高温蒸煮是一种彻底的工艺。温蒸煮温度范围一般在121-135℃之间，目前也有满足145℃超高温的软包装材料的研究。研究资料显示在145℃条件下，只要保持3min左右的处理时间，能把耐热的芽孢肉毒杆菌类有害病菌彻底杀灭，随此而产生的复合软包装材料也得到了广泛地应用。根据包装内容物的条件，本文讨论耐121℃高温的包装袋结构设计及加工工艺如何适应高温蒸煮的要求。

High temperature steaming is an efficient and thorough sterilization process. The temperature range for sterilization in warm cooking is generally between 121-135 ℃, and there is currently research on flexible packaging materials that can meet the ultra-high temperature sterilization requirements of 145 ℃. Research data shows that under the condition of 145 ℃, as long as the processing time is maintained for about 3 minutes, the most heat-resistant harmful bacteria such as Clostridium botulinum can be completely killed. The resulting composite flexible packaging materials have also been widely used. Based on the disinfection and sterilization conditions of the packaging contents, this article focuses on discussing how the structural design and processing technology of packaging bags that can withstand high temperatures of 121 ℃ can adapt to the requirements of high-temperature cooking.

的目的主要有两个：

The main purposes of sterilization are twofold:

1、对有害细菌消灭彻底，满足无菌的要求，如医疗用品的处理。

1. Thoroughly eliminate harmful bacteria and meet the requirements of sterility, such as sterilization treatment of medical supplies.

2、通过彻底后，在少加甚不加防腐剂的情况下能抑制细菌滋生，延长内容物的保质期，使内容物在常温下能较长久的保持原来设计的风味，如各种食品类高温蒸煮产品。

2. After thorough sterilization, bacterial growth can be suppressed with minimal or no preservatives added, extending the shelf life of the contents and allowing them to maintain their original design flavor for a longer period of time at room temperature, such as in various food high-temperature cooking products.

耐高温处理包装袋按当前国际上比较认可的分类如下：

The packaging bags for high-temperature sterilization treatment are classified according to the internationally recognized classification as follows:

1、可耐121℃的蒸煮袋，耐高温时间30-60min不等。

1. A steaming bag that can withstand 121 ℃ and can withstand high temperatures for 30-60 minutes.

2、可耐135℃的蒸煮袋，耐温时间15-30min不等。

2. A steaming bag that can withstand 135 ℃, with a temperature resistance time ranging from 15-30 minutes.

3、可耐145℃的超高温蒸煮袋，目前为别的蒸煮袋，耐温时间5min以下。

3. The ultra-high temperature steaming bag that can withstand 145 ℃ is currently the highest level of steaming bag, with a temperature resistance time of less than 5 minutes.

包装的工艺

Packaging process

1、复合工艺​

1. Composite process

复合包材的生产采用复合工艺，将不同的材料层紧密结合在一起。常见的复合方法有干式复合、挤出复合和共挤复合等。干式复合是通过胶粘剂将各层材料粘合，这种方法能实现不同性质材料的复合，但胶粘剂的选择关重要，必须确保其在高温蒸煮过程中不会释放有害物质，且粘合强度不受高温影响。挤出复合和共挤复合则是利用挤出机将熔融的塑料挤出并与其他材料复合，这两种方法生产效率高，且能保证复合层之间的结合紧密，减少空气和水分的渗透。​

The production of composite packaging materials adopts composite technology, which tightly combines different material layers together. Common composite methods include dry composite, extrusion composite, and co extrusion composite. Dry composite is a method of bonding various layers of materials together using adhesive, which can achieve the composite of materials with different properties. However, the selection of adhesive is crucial, as it must ensure that it does not release harmful substances during high-temperature cooking and that the bonding strength is not affected by high temperatures. Extrusion composite and co extrusion composite are methods that use an extruder to extrude molten plastic and composite it with other materials. These two methods have high production efficiency and can ensure tight bonding between the composite layers, reducing the penetration of air and moisture. ​

2、印刷工艺​

2. Printing process

为了提升产品的市场竞争力，复合包材通常需要进行印刷。在高温蒸煮包材的印刷过程中，要选用耐高温的油墨和印刷工艺。水性油墨由于其性和良好的耐高温性能，成为高温蒸煮包材印刷的。同时，在印刷过程中要控制好油墨的干燥程度和附着牢度，避免在高温蒸煮时出现油墨脱落、褪色等问题，影响食品的性和外观。

In order to enhance the market competitiveness of products, composite packaging materials usually require printing. In the printing process of high-temperature cooking packaging materials, high-temperature resistant ink and printing technology should be selected. Water based ink has become the preferred choice for printing high-temperature cooking packaging materials due to its environmental friendliness and excellent high-temperature resistance. At the same time, during the printing process, it is important to control the dryness and adhesion of the ink to avoid issues such as ink detachment and fading during high-temperature cooking, which can affect the safety and appearance of food.
