Packaging requirements
BARRIER CONTAINERS:
To enhance light, humidity and oxygen barrier properties , the bottles can be produced with the addition of barrier agents blended with the resin (nylon MXD6, EVOH, oxygen scavengers) or with the production of multilayer containers (PET+EVOH, PET+Nylon, PET+Nylon+scavenger).
HEAT SET AND PASTEURISABLE CONTAINERS:
SIPA offers many solutions for containers capable of resisting to hot fill (warm fill up to 75°C, hot fill up to 92 °C) or pasteurisation temperatures. SIPA is at the forefront of hot fill bottle design, with the lightest weights currently available on the market, above all in the neck area, guaranteeing the same performance as heavier containers. The panel area has also been optimised, with design solutions that allow more flexibility in the labelling and more attractive packaging
- Preserve CO2 levels inside the packaging. This is important especially for small size containers.
- Reduced bottle expansion due to internal pressure (Shape keeping).
- Containers must pass burst and drop tests.
- Shape and bottom designed to resist high internal pressure (creep and burst resistance).
- Reduce bottle weight while assuring bottle stability
