為了使用,使用塑料袋要注意什么?

說到塑料包裝袋,我們很熟悉,我們需要在日常生活的許多方面使用塑料袋。它很受歡迎,但是在使用它的時(shí)候我們需要注意一些事項(xiàng)。下面濟(jì)南復(fù)合塑料袋廠家為您講解:
When it comes to plastic packaging bags, we are very familiar with them. We need to use plastic bags in many aspects of daily life. It is very popular, but we need to pay attention to some things when using it. Below, Jinan composite plastic bag manufacturer will explain to you:
一般來說,我們每天生產(chǎn)的塑料包裝袋是沒有氣味的,但是如果有任何氣味,肯定會(huì)有問題,這會(huì)對(duì)食品產(chǎn)生很大影響。
Generally speaking, the plastic packaging bags we produce every day are odorless, but if there is any odor, there will definitely be problems, which will have a significant impact on food safety.
一是殘留溶劑:在配制過程中,食品塑料包裝袋上的有機(jī)溶劑不會(huì)揮發(fā)。當(dāng)“殘留溶劑”含量低于標(biāo)準(zhǔn)值時(shí),人們的嗅覺不會(huì)受到影響,也不會(huì)受到包裝食品味道的影響。如果“殘留溶劑”的含量超標(biāo),人們的嗅覺就會(huì)感覺到它的存在。當(dāng)消費(fèi)者打開高殘留溶劑的食品袋時(shí),他們會(huì)聞到與食品不同的“氣味”。
One is residual solvents: During the preparation process, the organic solvents on food plastic packaging bags will not evaporate. When the content of "residual solvents" is lower than the standard value, people's sense of smell will not be affected, nor will it be affected by the taste of packaged food. If the content of "residual solvent" exceeds the standard, people's sense of smell will sense its existence. When consumers open food bags with high residual solvents, they will smell a different "smell" from the food.

二是樹脂氧化氣味:擠壓復(fù)合是復(fù)合軟包裝材料的另一種復(fù)合工藝。在這個(gè)過程中,顆粒狀塑料樹脂需要在高溫下熔化,通過模具涂覆在其他基材上,然后冷卻并成型。如果溫度過高,塑料樹脂會(huì)被氧化分解,產(chǎn)生所謂的“樹脂氧化氣味”,可通過嚴(yán)格控制生產(chǎn)工藝條件加以。
The second is resin oxidation odor: extrusion composite is another composite process of composite soft packaging materials. In this process, granular plastic resin needs to be melted at high temperatures, coated on other substrates through molds, then cooled and formed. If the temperature is too high, the plastic resin will be oxidized and decomposed, producing the so-called "resin oxidation odor", which can be eliminated by strictly controlling the production process conditions.
為了延長(zhǎng)保質(zhì)期,方便運(yùn)輸?shù)礁鞯劁N售,市場(chǎng)上很合多食品都會(huì)選擇包裝袋進(jìn)行包裝,但并非所有的包裝袋產(chǎn)品都適合包裝。我們?cè)诎b前選擇的材料也可以說直接關(guān)系到它們是否適包裝食品。
In order to extend the shelf life and facilitate transportation to various regions for sales, many foods in the market choose packaging bags for packaging, but not all packaging bag products are suitable for packaging. The materials we choose before packaging can also directly affect whether they are suitable for packaging food.
塑料袋可以防潮。當(dāng)我們用它們來儲(chǔ)存物品時(shí),它們可以起到防潮的作用。由于其透明的外觀,我們可以從外部看到內(nèi)部包含的項(xiàng)目。也方便大家區(qū)分,不需要一一打開。更多相關(guān)產(chǎn)品事項(xiàng)就來我們網(wǎng)站http://m.treacyeller.com咨詢吧!
Plastic bags can prevent moisture. When we use them to store items, they can play a moisture-proof role. Due to its transparent appearance, we can see the items contained internally from the outside. It is also convenient for everyone to distinguish and does not need to be opened one by one. For more product related matters, come to our website http://m.treacyeller.com Consult!
