來源:m.jwwylp.com 發(fā)布時間:2023-05-15 瀏覽次數(shù):122
外賣打包袋必須能夠經(jīng)受低溫和高溫,以便適合冷凍或烹飪食物。它還應(yīng)具有較強(qiáng)的韌性和抗損壞能力,以免暴露食品,造成食品變質(zhì)。它還具有很強(qiáng)的阻擋能力,灰塵、水分和空氣的進(jìn)入,并應(yīng)具有很強(qiáng)的遮陽能力,以避免外界因素引起的食物變質(zhì)。這樣一來,我們就應(yīng)該注意選擇塑料袋,以免影響正常使用。
Delivery bags must be able to withstand low and high temperatures in order to be suitable for freezing or cooking food. It should also have strong toughness and damage resistance to avoid exposing food and causing it to spoil. It also has strong blocking ability to prevent the entry of dust, moisture, and air, and should have strong shading ability to avoid food spoilage caused by external factors. In this way, we should pay attention to choosing plastic bags to avoid affecting normal use.
1、外賣打包袋在自然環(huán)境下即在陽光直射的條件下,一周后其強(qiáng)度下降約25%,兩周后會下降約40%,基本上已不能運(yùn)用。也就是說塑料打包袋的貯存保管問題非常重要。
1. In natural environments, such as direct sunlight, the strength of takeout bags decreases by about 25% after one week and by about 40% after two weeks, making them basically unusable. That is to say, the storage and storage of plastic packaging bags are very important.
2、打包袋在包裝了物品之后放在露天環(huán)境受陽光直射,強(qiáng)度會急劇下降,所以要盡量避免陽光的直射。
2. After packaging the items, the packaging bag will be exposed to direct sunlight in the open air, and its strength will sharply decrease. Therefore, it is necessary to try to avoid direct sunlight.
3、再生料的過多參加也是促進(jìn)塑料打包袋老化的原因之一。
3. The excessive participation of recycled materials is also one of the reasons for promoting the aging of plastic packaging bags.
4、打包袋貯運(yùn)過程中溫度過高或遇到雨淋,都會導(dǎo)致其強(qiáng)度下降,然后達(dá)不到維護(hù)內(nèi)裝物品的質(zhì)量要求,所以在平時應(yīng)該避免高溫和雨水的沖刷。
4. During the storage and transportation of packaging bags, if the temperature is too high or they encounter rain, their strength will decrease, and they will not meet the quality requirements for maintaining the contents. Therefore, it is important to avoid the erosion of high temperature and rain in daily life
外賣打包袋
如今社會當(dāng)中,很多陳列在柜臺上面的外賣打包袋大部分都是帶有鋸齒,其目的就是便于消費(fèi)者扯開袋子,更方便的打開打包袋,但是你有沒有想過,為什么會弄成鋸齒狀的效果,而不是平口的效果,打包袋為什么要制作成鋸齒口。
In today's society, many takeout bags displayed on the counter are mostly equipped with serrations, with the purpose of making it easier for consumers to open the bag and open it more conveniently. However, have you ever thought about why they have a serrated effect instead of a flat one, and why packaging bags need to be made with serrated openings.
這個問題涉及到力學(xué)的使用,當(dāng)物體受力的時候,受力會根據(jù)物體本身外形而改動,一般會在褶皺或者尖角處發(fā)作突變。因此打包袋廠把袋子邊緣制作成鋸齒狀,保留這個鋸齒狀的效果,可以讓消費(fèi)者很輕松、方便的打開打包袋。更多相關(guān)的事項(xiàng)就來咨詢我們http://m.jwwylp.com!
This issue involves the use of mechanics. When an object is subjected to force, the force will change according to the shape of the object itself, usually causing sudden changes in folds or sharp corners. Therefore, the packaging bag factory makes the edge of the bag into a serrated shape, retaining this serrated effect, which can make it easy and convenient for consumers to open the packaging bag.
