Whether it is during transportation and loading and unloading, or in supermarket storage. The stacking pressure caused by the backlog of goods on the upper layer (especially large bottles) must be taken into account, so the bottom bearing capacity must be sufficient, otherwise it is easy to cause the bottle to collapse and indirectly affect the sales of the product.
—Size and weight of preform—
* Balance between lightness and strength: It is necessary to consider the higher the strength requirements of stacking, and the weight should be increased when selecting bottle embryos to cope with transportation and storage conditions. Then, under the premise of ensuring the strength after blowing, the weight of a single bottle embryo is reduced to reduce costs. Our company provides multiple specifications for you to choose for testing and adaptation.
* Bottle embryo shape
Wall thickness uniformity: Ensure that the bottle embryo is not easy to deform or break during transportation.
Bottle mouth support ring: The sturdy support ring effectively prevents the deformation of the bottle embryo due to long-term mutual squeezing in the package
Based on the accumulated production experience and customer feedback. Our engineers have optimized the above-mentioned bottle embryo structure to ensure that we can provide you with high-quality and easy-to-use bottle embryos.
—The packaging method determines the protection of the preform and precautions—
PET material has strong hygroscopicity. If the humidity in the warehouse is not well controlled, the quality of the blow-molded bottle will be affected if it is stored for a long time. In addition, when the preform is piled up to more than 3 meters, the bottom preform mouth is easily deformed by pressure. Therefore, attention should be paid to the storage conditions to ensure the normal use of the product. Different packaging methods are also areas that need to be considered. The following is a comparison of packaging methods:
1. Carton/turnover box packaging:
*Advantages: good protection, reusable, suitable for automated handling
The box size is suitable for pallets. It is the first choice for large-scale and long-distance transportation (such as sea transportation)
2. Fiber bag packaging
*Low cost but limited protection; it is easy to cause scratches on the bottle mouth or product contamination during loading and unloading or transit transportation
The selection of preforms is essentially the starting point for the design of supply chain efficiency. Various factors in actual use scenarios are often easily overlooked, but they will directly affect the performance of the bottle. An excellent preform solution can reduce your logistics costs by more than 20% - the process from injection molding machine to blow molding machine determines the competitiveness of the entire packaging system.
