We know that large shopping centers and supermarkets will customize Jinan plastic bags with their own logo, and the plastic bags used by enterprises will be printed with enterprise logo and related content. Therefore, it is necessary to order plastic bags. So, what should we pay attention to when ordering plastic bags?

1.選擇塑料袋廠家

1. Select plastic bag manufacturer

如今，塑料袋的生產已在一定程度上被禁止和管制，但即便如此，仍然有許多非法制造塑料袋的制造商。因此，在選擇制造商時，有必要選擇制造商的常規安全措施，以確保定制的塑料袋可以投放市場并且安全，特別是在食品塑料袋方面。

Today, the production of plastic bags has been banned and regulated to some extent, but even so, there are still many manufacturers who illegally manufacture plastic bags. Therefore, when selecting manufacturers, it is necessary to select the manufacturer's conventional safety measures to ensure that customized plastic bags can be put on the market and safe, especially in food plastic bags.

2.材料選擇

2. Material selection

定制塑料袋時，請確保選擇正確的材料。目前，塑料袋生產的主要材料是聚乙烯和聚丙烯。前者是無毒和環保的，而后者是有毒和有害的，但不是環保的。因此，使用和使用之間存在很大差異。在定制中，根據您的塑料袋的用途選擇合適的材料。

When customizing plastic bags, make sure to select the correct materials. At present, the main materials of plastic bag production are polyethylene and polypropylene. The former is non-toxic and environmentally friendly, while the latter is toxic and harmful, but not environmentally friendly. Therefore, there are great differences between use and use. In customization, select the appropriate materials according to the purpose of your plastic bag.

3.選擇規格和尺寸

3. Select specifications and dimensions

如果是定制塑料袋，則尺寸可以自己決定。以超市的便利袋為例。一般來說，在工廠中，大，中，小三種類型的袋子并沒有完全統一。有時，可以根據超市的特定需求調整模型。而且，超市便利袋必須印有國家統一的連鎖標志，食品安全袋等，并印有與食品安全有關的標志，才能投入使用。

If it is a custom plastic bag, the size can be determined by yourself. Take the convenience bag in the supermarket as an example. Generally speaking, in the factory, the three types of bags, large, medium and small, are not completely unified. Sometimes, the model can be adjusted according to the specific needs of the supermarket. Moreover, supermarket convenience bags must be printed with national unified chain signs, food safety bags, etc., and signs related to food safety before they can be put into use.
