Why do custom packaging bags have to provide dimensions？

Many customers do not know the size of the packaging bag when purchasing the packaging bag, and only provide the manufacturer with the weight of the entire product, about how many grams. However, the weight is not useful to the packaging bag manufacturer. The packaging bags required for the same weight of different products are not the same. Only the customer knows what size packaging bags to use.

And there are many different types of packaging bags, such as eight-side sealing, three-side sealing, vacuum bags and so on. Many customers only provide the weight of the product, but let the manufacturer make it. The final packaging bag does not meet the customer's requirements, which will waste a lot of time and cost.

Before this, I cooperated with a foreign customer, the customer asked us to provide 500g pet food packaging bags, but did not provide the size. Finally, we set the size of a 500g pet food packaging bag according to our experience, and produced a batch of goods. However, after receiving the goods, the customer found that the length was a bit long when packing, which greatly affected the appearance. This resulted in an unpleasant collaboration.

Since it takes a long time and energy to produce packaging bags each time, customers need to measure the size of packaging bags suitable for packaging their own products, so as to conveniently and accurately produce packaging bags required by customers and improve efficiency.
