How to Distinguish between Environmentally-friendly Bubble Bags And Non-environment-friendly Bubble Bags?
1. There is a concept of original meter and non original meter in the bubble film. The original meter is the first material to participate in production. The corresponding non original meter is the recycled material mixed with old materials or even waste materials. The original meter bubble film has bright luster, good transparency and toughness, but the color of the non original meter is dim or even black, which is easy to deflate. Although the non original rice bubble film also has the effect of shockproof, it obviously reduces your baby's image, so you must ask several more before you buy it. If you encounter a bubble film that is obviously much cheaper than other houses, you should have many hearts and eyes, and don't lose your heart for small reasons.
2. There are many properties of bubble membrane, such as the difference between big bubble and small bubble. The standard diameter of big bubble is 1cm, while that of small bubble is 0.5cm, the height of big bubble is 0.35cm, and that of small bubble is 0.25cm, The shockproof effect of big bubble is much better than that of small bubble, and there are two types in big bubble: big bubble thickening type and big bubble ordinary type, mainly the thickness of each bubble and bubble pad. Generally speaking, the 100 meter thick bubble film with a width of 60cm should be more than 2.5kg to be qualified, while the ordinary bubble film with a width of 2kg to be qualified.
3. Get out of the bubble membrane mistake: the first reflection of many buyers after buying bubble membrane is how the bubble is not so full. In fact, just like the balloon, the balloons with more bulge are more likely to break, while the balloons with less air are not so easy to break. The reason is that when the commodity is placed on the bubble membrane, the bubble is too easy to bear the item at a point, and if not, the weight of the item will be divided Spread out on one surface, the weight that one surface can bear must be larger than that of one point. Therefore, when purchasing bubble film, don't think that there is not enough air to pursue bubble film. Generally speaking, air is enough for 2 / 3 of each bubble, which is the most ideal
The new material bubble bag is very white without any impurities. If there is recycled material, the price is cheaper, but the color is dark yellow, which can only be used for turnover, not suitable for packaging finished products.
