Changzhou plastic bag manufacturers: What should you pay attention to when buying plastic bags?
Changzhou plastic bag manufacturers: Plastic bags are odorless when they leave the factory. However, some unscrupulous manufacturers, in order to save costs, use waste materials for production. Packaging bags made from these waste materials generally emit a pungent odor and are likely to cause secondary pollution to the packaged products. Therefore, it is best to buy products without any strange smell.
The outer packaging should have the manufacturer's markings. Reputable manufacturers will indicate the manufacturer's name, address, and the full name of the product company on the outer packaging bag. This makes it easy to trace the manufacturer if there are any quality issues.
Good quality packaging bags are generally not cheap because good products are made from brand-new materials, which have higher costs, so the prices are generally not low.
However, you get what you pay for. Bags with good quality are generally made from new materials. Low-priced bags are usually made from recycled materials, and their quality is not guaranteed, making them unsuitable for direct food packaging. The choice depends on your packaging needs.
If packaging performance allows, try to choose thinner packaging bags. Why? Thinner bags have a lower unit price, saving packaging costs. Secondly, thinner bags are easier to degrade, reducing environmental pollution, as thinner bags align with the concept of green packaging.
Try to choose packaging bags without coatings or with environmentally friendly coating materials. Many coated materials are used for aesthetics and corrosion resistance. However, this not only makes the materials difficult to recycle after the product is discarded but also makes most coatings themselves toxic.
Changzhou plastic bag manufacturers: How to distinguish between different types of plastic bags?
Currently, there are two types of plastic bags on the market, distinguished by whether they are for food packaging. Food packaging needs to meet food safety requirements and can be directly used to package cooked food, pastries, etc. So how do you distinguish between different types of plastic bags? This article will give you a brief introduction.
From the perspective of plastic bag production, the cost of ordinary plastic bags is much lower than that of food-grade bags. In addition, the price of raw materials is also much cheaper. Secondly, the QS mark should be printed on food-grade bags. If an additional printing process is added, the production cost will increase. Even the production of this product is very simple. Many family workshops have added several sealing and cutting machines and have been processing for many years without stopping. This product contains more than 5% oxalic acid and should not be in direct contact with food.
Changzhou plastic bag manufacturers: Although plastic bags are often free, you should choose suitable products for different products (especially cooked food). We need to choose food-grade bags. For other items, you can use them wisely, but if you can reuse them, it's worthwhile.
The above is an explanation of what to pay attention to when purchasing plastic bags in Changzhou. Have you all understood? If you want to learn more about plastic bags in Changzhou, please feel free to contact us. Thank you for watching, and see you next time.
