selection for clamshell packaging
Sometimes customers ask which clamshell packaging material is cheaper or better for their products, in fact from our point of view there are no cheaper or better materials. The material we choose should be compatible with our products and their functions. For example, if we need a clamshell for food, we should choose PET, or if we need blister packaging for hardware, PVC is better choice.
Although PVC and PET are both clamshell and blister packaging materials, and the price of PVC is cheaper than PET, but PVC is not an environmentally friendly material, it cannot use directly for food. So if we use PVC clamshell for food, we have to make another bag packaging first and then put it into the clamshell. This is a waste of material and time. So in this situation, we should choose PET directly.
PVC is not environmentally friendly, but the cost is lower than others, it will be a good choice if we use it to the hardware tools products. PET material is environmentally friendly and anti-static material, so if customers said they need anti-static material, we recommend PET or PS.
In summary, the selection of materials for clamshell packaging must take into account product characteristics, packaging requirements, cost and other factors, the In the high-temperature environment may release harmful substances, less suitable for packaging food and other products with high safety requirements; its waste in the natural environment is difficult to degrade, a certain degree of environmental pollution.are some common clamshell packaging materials and their characteristics, so that you can choose according to the actual situation:
