Continuous roll bags are a common packaging bag in daily life. The so-called continuous roll bags are those that are connected one by one, rolled up into bundles, and gently pulled according to the cut gaps when used to create a bag for easy storage and use. But since the release of the plastic restriction order, plastic bags in supermarkets and stores have to be purchased, so we habitually take a few more roll up bags as backup when buying vegetables or fresh food. This can save the cost of plastic bags. The widespread use of roll wrap bags in supermarkets has made shopping easier for consumers, making them not only safe but also reusable. The quality of a continuous roll bag largely determines its suitability for food, household use, and impact on human health. Therefore, distinguishing the good and bad of a continuous roll bag has become an important skill.
Now let's teach you how to distinguish the quality of continuous roll bags:
1.1 First, distinguish from the appearance. Some even rolled bags are pure and transparent, with a flat surface and a smooth feel. Some are dark and opaque, with a cloudy and matte surface and a slightly sticky feel. Therefore, when choosing, it is best to choose natural and transparent roll up bags for better safety performance, as dark and opaque bags are mostly made from recycled shopping bags, plastic bags, etc. for secondary use and cannot be used as food packaging bags. However, in the production process of continuous roll bags, some manufacturers will print the words "for food use" on the surface of the continuous roll bags, making it easier for everyone to distinguish the practical scope of the continuous roll bags.
2. By observing the combustibles of the continuous roll bag after combustion, it can be determined that if the continuous roll bag is flammable and has a wax like odor during the combustion process, and produces drop-shaped substances like candle oil, it is a qualified and high-quality plastic bag, free from waste or garbage plastic, suitable for food use, health and safety; If it is not easy to burn and emits irritating black smoke during the combustion process, it is considered an unqualified plastic bag, indicating the presence of waste plastic and garbage plastic.
Plastic bags themselves are not easily degradable and have low recycling rates, which can lead to resource waste and environmental pollution. So choosing a safe, healthy and reliable roll bag not only improves people's daily health and safety quality, but also helps to protect the environment to a certain extent.
