Three Minutes to Decode the Plastic Juice Bottle before Molding

Plastic Juice bottles need us to pay attention to some details before molding. In particular, we need to pay attention to the fact that the shape of the plastic bottles must have symmetry. In other words, juice bottle manufactures have to reduce the extreme stretch points and locations. And arc transitions are needed in all transitions. What are the specific issues that need to be taken into account before molding IPEC plastic bottles?


1. Let the plastic bottle be uniform on the wall thickness. This is where all consumers pay the most attention. Especially on the outer surface of the printing should be flat, continuous; if the liquid plastic bottle contains handles, grooves, ribs and other structures.

2. in the printing surface of plastic bottles. When designing, care should be taken not to cause an inconvenience to the printing operation. Need to make the label surface flat. A “sash” can be designed on the outside of the plastic bottle to accurately position the label.

3. plastic bottles used when the appearance of the label. No movement. For example, the middle of a plastic bottle is relatively small.

4. change the shape of the appearance of plastic bottles. This we can increase the peripheral grooves and ribs on the outer surface of plastic bottles, which can improve the rigidity and bending resistance of plastic bottles. However, if it is a longitudinal groove and a stiffener, it can eliminate the plastic bottle's offset, sagging and deformation under the temporary load.

5. When we design extruded plastic bottles. The cross-section of a plastic bottle needs to be rectangular or oval, whereas for a flexible plastic bottle, the cross-section inside is preferably round. This makes it easier to squeeze the contents inside out of the plastic bottle.

6. when blow molding. First of all, you must tend to harden the area first. In this way, the wall thickness of this part will also be larger. Where the edges and corners are, but when the parison blows up to the point of last contact, the wall thickness of the part will also be smaller. Therefore, the edge of the plastic bottle and the place to wipe the corner need to be rounded.
