濟(jì)南復(fù)合塑料袋如何復(fù)合高溫蒸煮工藝

來源:http://m.ttw234.com/ 日期:2025-04-18

高溫蒸煮是一種徹底的工藝。溫蒸煮溫度范圍一般在121-135℃之間,目前也有滿足145℃超高溫的軟包裝材料的研究。研究資料顯示在145℃條件下,只要保持3min左右的處理時間,能把耐熱的芽孢肉毒桿菌類有害病菌徹底殺滅,隨此而產(chǎn)生的復(fù)合軟包裝材料也得到了廣泛地應(yīng)用。根據(jù)包裝內(nèi)容物的條件,本文討論耐121℃高溫的包裝袋結(jié)構(gòu)設(shè)計及加工工藝如何適應(yīng)高溫蒸煮的要求。

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.

的目的主要有兩個:

The main purposes of sterilization are twofold:

1、對有害細(xì)菌消滅徹底,滿足無菌的要求,如醫(yī)療用品的處理。

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

2、通過徹底后,在少加甚不加防腐劑的情況下能抑制細(xì)菌滋生,延長內(nèi)容物的保質(zhì)期,使內(nèi)容物在常溫下能較長久的保持原來設(shè)計的風(fēng)味,如各種食品類高溫蒸煮產(chǎn)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.

耐高溫處理包裝袋按當(dāng)前國際上比較認(rèn)可的分類如下:

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,耐高溫時間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,耐溫時間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℃的超高溫蒸煮袋,目前為別的蒸煮袋,耐溫時間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.

包裝的工藝

Packaging process

1、復(fù)合工藝?

1. Composite process

復(fù)合包材的生產(chǎn)采用復(fù)合工藝,將不同的材料層緊密結(jié)合在一起。常見的復(fù)合方法有干式復(fù)合、擠出復(fù)合和共擠復(fù)合等。干式復(fù)合是通過膠粘劑將各層材料粘合,這種方法能實現(xiàn)不同性質(zhì)材料的復(fù)合,但膠粘劑的選擇關(guān)重要,必須確保其在高溫蒸煮過程中不會釋放有害物質(zhì),且粘合強(qiáng)度不受高溫影響。擠出復(fù)合和共擠復(fù)合則是利用擠出機(jī)將熔融的塑料擠出并與其他材料復(fù)合,這兩種方法生產(chǎn)效率高,且能保證復(fù)合層之間的結(jié)合緊密,減少空氣和水分的滲透。?

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、印刷工藝?

2. Printing process

為了提升產(chǎn)品的市場競爭力,復(fù)合包材通常需要進(jìn)行印刷。在高溫蒸煮包材的印刷過程中,要選用耐高溫的油墨和印刷工藝。水性油墨由于其性和良好的耐高溫性能,成為高溫蒸煮包材印刷的。同時,在印刷過程中要控制好油墨的干燥程度和附著牢度,避免在高溫蒸煮時出現(xiàn)油墨脫落、褪色等問題,影響食品的性和外觀。

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.
