外卖打包袋必须能够经受低温和高温,以便适合冷冻或烹饪食物。它还应具有较强的韧性和抗损坏能力,以免暴露食品,造成食品变质。它还具有很强的阻挡能力,灰尘、水分和空气的进入,并应具有很强的遮阳能力,以避免外界因素引起的食物变质。这样一来,我们就应该注意选择塑料袋,以免影响正常使用。
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、外卖打包袋在自然环境下即在阳光直射的条件下,一周后其强度下降约25%,两周后会下降约40%,基本上已不能运用。也就是说塑料打包袋的贮存保管问题非常重要。
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、打包袋在包装了物品之后放在露天环境受阳光直射,强度会急剧下降,所以要尽量避免阳光的直射。
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、再生料的过多参加也是促进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、打包袋贮运过程中温度过高或遇到雨淋,都会导致其强度下降,然后达不到维护内装物品的质量要求,所以在平时应该避免高温和雨水的冲刷。
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
如今社会当中,很多陈列在柜台上面的外卖打包袋大部分都是带有锯齿,其目的就是便于消费者扯开袋子,更方便的打开打包袋,但是你有没有想过,为什么会弄成锯齿状的效果,而不是平口的效果,打包袋为什么要制作成锯齿口。
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.
这个问题涉及到力学的使用,当物体受力的时候,受力会根据物体本身外形而改动,一般会在褶皱或者尖角处发作突变。因此打包袋厂把袋子边缘制作成锯齿状,保留这个锯齿状的效果,可以让消费者很轻松、方便的打开打包袋。更多相关的事项就来咨询我们//www.katc3.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.
