What is the difference between the inside and outside dimensions of food packaging?
The size of food packaging can be divided into external dimension and internal dimension. For ordinary food packaging, the difference between inner diameter and outer diameter is not big. Food packaging can be classified by material, such as: paper box, corrugated box, pet box, etc., or by product name, such as: moon cake box, tea box, medlar box, candy box, exquisite gift box, local specialty box, makron box, chocolate box, etc. For high-end hand-made boxes, the internal and external dimensions are very different, often reaching the difference of CM. If the internal and external dimensions are not clear, a very large error may occur. It may cause that the internal support cannot be put in, the paper bag is not allowed, etc. Many customers don't understand this. Here's a detailed description of the inside and outside dimensions.
The first thing to know is what is the inside and outside size of the box. The outside size is actually the size of the box that we often measure. Use a ruler to measure the size of the box. The internal dimension is to put the ruler into the box and measure the internal volume of the box. The difference between them is the thickness of the box material. If paper jam is used, the thickness will not exceed 3mm generally. As a result, the internal and external dimensions are not very different, but if the box is made by hand, the material will even reach 3cm. In this way, there is a big difference between the internal and external dimensions. Some customized food packaging manufacturers, if the internal size is the external size, will cause the wrong size of the packaging box, the product can not be loaded.
Generally do not know the internal and external dimensions of customers, the reported dimensions are mostly external dimensions. So when customizing the packing box, there is no problem to know the internal and external dimensions. The above is about the internal and external dimensions of customized food packaging.
