Filling process
- High wall thickness to yield thicker bottle.
- Optimum design for strain hardening & crystallinity.
- Too much stretching can lead to residual stresses at final bottle, leading to higher shrinkage.
- Crystallized neck to withstand temperature during filling.
- Wide / thick neck to avoid contact of hot liquid & deformation.
- Crystallized neck to withstand temperature during filling.
- Wide / thick neck to avoid contact of hot liquid & deformation.
- Panels to absorb and dissipate vacuum created in bottle during cooling of content.
- Base ribs to withstand temperature and liquid filling force.
- Rigid circular ribs withstand deforming forces.
- Higher post mold shrinkage allowance in mold design.
- Less than 1% thermal shrinkage on hot filling conditions.
- Base clearance to be maintained.
- No unequal deformation in base leading to tilting / rocking of bottles.
- No warping at neck seal surface.
- No leakage at seal surface.
- Tilt bottle to wet & warm the closure immediately after capping.
- Water shower the bottle to lower temperature, before putting on shrink sleeve label.
- Water quality in shower to be clean, in order to avoid mold growth between the bottle & shrink film / pilfer proof ring.
- Closure material to take care of content temperature at filling.
- Single piece closure to avoid the effect of warping of wad.
- Sealing surfaces to take care of the expansion & shrinkage during filling and cooling.
- Higher perform temperature for blowing.
- Hot blow mold surfaces to increase the bottle wall crystallinity through thermal crystallization.
- Reduce the orientation stresses in the bottle wall.
- Internal cooling of bottle by stretch rod, to harden inner wall before ejection.
- Quick opening of mold cavities to avoid softening of bottle wall after cooling.
- Fill close to brimful in crystallized neck finish.
- Fill up to NSR (Neck Support Ring) in non-crystallized neck finish.
- Contact of high temperature filling head with the Non-crystallized neck finish avoided.
- Quick capping, to avoid product contact with ambient air & cooling.
- Caps to be sterilized before capping
