How to Choose a Suitable PE or EVA Plastic Packaging Bag for Your Chemical Products
1. Determine whether the product to be packaged is in powder, flake, or granular form.
For powders, the primary concerns are dust prevention and leakage avoidance to prevent contamination of the workshop environment. granular or flake using the normal PE valve bag is ok.
2. Consider the weight capacity of the plastic bag, which typically comes in 15kg, 20kg, 25kg, and 50kg. Different weights require different thicknesses of the bag.
3. Identify the melting point of the bag. Bags with a melting point generally above 90°C are referred to as EVA low-melting-point feeding bags or hot-melt bags. These are commonly used in the rubber industry, where the bag can be directly thrown into a mixer or kneader without unpacking. The bag melts at high temperatures and integrates with the rubber material without affecting its performance. Another type is the ordinary PE bag, which has a melting temperature above 120°C and requires unpacking before use.
4. Regarding the filling machine, it is necessary to clarify whether it is manual or automatic filling. Different filling methods require different materials for the valve port. now the famous automatic filling machine is Harver&Boeker. our bag special suitable for them.
5. The size of the bag's valve port must match the diameter of the filling machine's filling tube.
By clarifying the above information, you can essentially determine the required bag specifications. Panteto can design and customize solutions for customers to ensure the bags meet the ideal usage conditions.
