Foam packaging, in short, is the packaging made of foam. Generally speaking, the foam packaging is mainly made of expandable polystyrene (EPS) raw materials by hot processing through molds. The packaging products produced are commonly known as "foam". Expandable polystyrene is an ideal packaging material that can be processed into various shapes and thicknesses of packaging products according to needs through molding processes. Under high loads, materials achieve cushioning and shock absorption through deformation, energy absorption, and decomposition, while also having insulation and insulation functions. EPS packaging products are generally white and can be produced in color according to requirements.

Foam packaging is not in a completely dry state as we have seen, and there is a certain amount of moisture inside. Maybe everyone will have this question: Where does the water in the foam package come from? How does the moisture in foam affect foam packaging? The moisture content of foam packaging will be introduced below.

We will discuss the source of water in foam packaging. The water in foam packaging mainly comes from two sources: on the one hand, it is the direct source of production technology; on the other hand, it is the water generated by the chemical reaction inside foam packaging. Secondly, we want to talk about the influence of moisture on foam packaging. A large number of experimental studies have proved that too much moisture will have many adverse effects on foam packaging processing, including overflow, bubbles, looseness, deformation, warpage, wrinkling and other defects. Of course, the water content of foam packaging is not as small as possible. Low water content can also bring many problems, including forming difficulties and ingot pressing difficulties.

Through the above explanation, I believe everyone is very clear about the source and harm of water in foam packaging. Therefore, Qingdao Rongfa InsulationFoam packaging manufacturerRemind everyone to reduce the absorption of water during transportation and storage when using foam packaging in daily life to ensure the functional integrity of foam packaging.
