復(fù)合袋的主要用途是包裝食品、藥品等，因此，復(fù)合袋的衛(wèi)生性是一項(xiàng)重要的指標(biāo)，隨著衛(wèi)生法規(guī)的完善和消費(fèi)者意識(shí)的提高，其要求還會(huì)進(jìn)一步提高。那影響濟(jì)南復(fù)合袋衛(wèi)生性的因素有哪些呢？

The main use of composite bags is to package food, medicine, etc. Therefore, the hygiene of composite bags is an important indicator. With the improvement of national health regulations and the improvement of consumer awareness, its requirements will be further improved. What are the factors that affect the hygiene of Jinan composite bags?

復(fù)合基材的影響

Effect of composite substrate

只有在復(fù)合基材的衛(wèi)生性確保的前提下，才能加工成符合衛(wèi)生的復(fù)合袋。復(fù)合基材有各種塑料膜、鋁箔、鍍鋁膜等，在食品及藥品包裝袋上，這些基材應(yīng)該、無(wú)臭、無(wú)味，衛(wèi)生指標(biāo)合格。在各種復(fù)合基材中，影響大的是復(fù)合袋內(nèi)層基材，它直接與包裝袋的內(nèi)容物接觸，內(nèi)層基材除少量用EVA/EAA/EEA之外，絕大多數(shù)是采用PE和PP。

Only on the premise that the hygiene of the composite substrate is ensured, can the composite bag be processed into a hygienic and safe composite bag. Composite substrates include various plastic films, aluminum foils, aluminized films, etc. On food and drug packaging bags, these substrates should be non-toxic, odorless, tasteless, and have qualified health and safety indicators. Among all kinds of composite base materials, the most influential one is the inner base material of the composite bag, which is directly in contact with the contents of the packaging bag. In addition to a small amount of EVA/EAA/EEA, the inner base material is mostly PE and PP.

輔助材料的影響

Influence of auxiliary materials

復(fù)合袋正常工藝中，需要用到大量輔助材料，主要輔助材料有油墨、粘合劑、溶劑、爽滑粉等。由于輔助材料的特殊性，對(duì)復(fù)合袋的衛(wèi)生性影響大，因?yàn)檫@些有機(jī)低分子物質(zhì)可透過(guò)復(fù)合內(nèi)層遷移到食品和藥品中去。

In the normal process of composite bags, a large number of auxiliary materials need to be used. The main auxiliary materials include ink, adhesive, solvent, slippery powder, etc. Due to the particularity of auxiliary materials, the hygiene of composite bags is greatly affected, because these organic low-molecular substances can migrate into food and medicine through the composite inner layer.

環(huán)境衛(wèi)生的影響

Impact of environmental sanitation

復(fù)合袋的生產(chǎn)要經(jīng)過(guò)許多環(huán)節(jié)和工序，為此，生產(chǎn)加工轉(zhuǎn)移、儲(chǔ)存中的環(huán)境衛(wèi)生也是重要的，制造設(shè)備應(yīng)保持清潔，制造設(shè)備不可有毒，化學(xué)品倉(cāng)庫(kù)應(yīng)保持正壓，倉(cāng)庫(kù)要清潔。

The production of composite bags needs to go through many links and processes. Therefore, the environmental sanitation during production, processing, transfer and storage is also important. The manufacturing equipment should be kept clean, the manufacturing equipment should not be toxic, the chemical warehouse should be kept under positive pressure, and the warehouse should be clean.
