我國(guó)的制袋生產(chǎn)廠家過(guò)去主要以生產(chǎn)窄幅全自動(dòng)制袋機(jī)為主，近年來(lái)，隨著需求的增加，在我們食用物資供應(yīng)的背后，是制袋機(jī)包裝市場(chǎng)提供了幫助。
在制袋過(guò)程中也常常遇到熱封性能不好的問(wèn)題，我們?cè)撊绾谓鉀Q呢？采用保溫老化加快粘合劑硬化，這樣可以提高復(fù)合膜的強(qiáng)度及耐熱性。
選擇熱封條件時(shí)，根據(jù)復(fù)合薄膜的結(jié)構(gòu)、熱封狀態(tài)等情況選擇，或者改進(jìn)熱封方式，熱封后及時(shí)冷卻。
定期檢查熱封層薄膜的保質(zhì)期和保存條件，要注意舊批號(hào)或熱封過(guò)的薄膜。
改變熱封層薄膜的種類(lèi)，選擇具有抗污染熱封性的內(nèi)封層薄膜。
熱封后檢測(cè)熱封面的處理程度，調(diào)節(jié)適宜的熱封溫度。
現(xiàn)如今，制袋機(jī)被運(yùn)用在食品、化工等國(guó)計(jì)民生的重大產(chǎn)業(yè)，運(yùn)用就可能遇到其他問(wèn)題。
學(xué)會(huì)怎樣解決，才能讓制袋機(jī)達(dá)到人們的需求。

　　In recent years, with the increase of demand, behind the supply of our food materials, is the help of the packaging market. In the process of bag making, we often encounter the problem of poor heat sealing performance. How can we solve it? The strength and heat resistance of the composite film can be improved by using heat preservation aging to accelerate the hardening of the adhesive. When selecting the heat sealing conditions, choose according to the structure and heat sealing state of the composite film, or improve the heat sealing mode, and cool in time after heat sealing. Regularly check the shelf life and preservation conditions of the heat sealed film, and pay attention to the old batch number or the heat sealed film. Change the type of heat sealing film, choose the inner sealing film with anti pollution heat sealing property. After heat sealing, check the treatment degree of heat sealing surface and adjust the appropriate heat sealing temperature. Nowadays, the bag making machine is used in the food, chemical industry and other major industries of national economy and people's livelihood, which may encounter other problems. Learn how to solve it, so that the bag making machine can meet people's needs.
