ACTUAL ALTERNATIVE ON THE MARKET AND RELATIVE ADVANTAGE /DISADVANTAGE
Advantages:
- Great clarity
- Great heat resistance
- Great vaccum resistance
Disadvantages:
- Heavy weight
- Fragile
- High risk of micro splinters
- Low resistance to “termic jumps”
- Glass suppliers price policy not always very “transparent”
- High logistic costs
- Low possibility to play with various shapes and colors
Advantages:
- Low weight
- Unbreakable Sufficent oxygen barrier
- Great Opportunity for graphic decorations
- Well known technology
Disadvantages:
- Few shapes
- Low commercial appeal (low ability to personalize)
- Not an ergonomic packaging
- Not a clear packaging
- Low recyclability (layers are made with different materials)
Advantages:
- Good heat resistance
- Unbreakable
- Allows to have both jar/bottle and cap in plastic (mono-packaging)
- Low weight
- Allows to play with shapes and decorations
Disadvantages:
- Low clarity
- Low recyclability due to the different layers in the Coex (for example Polypropylene with EVOH or NYLON)
- The cost is normally higher than glass
Advantages:
- Sufficient clarity
- Good oxygen barrier
- Allows to play with shapes and colors
- Unbreakable
- Allows to have both jar/bottle and cap in plastic (mono-packaging)
- Low weight
- Possibility of “in-house” production with the relative logistic cost savings (less used storage space of the incoming preform compared with the other empty packaging) and better hot filling performance.
Disadvantages:
- Low heat resistance
- High cost (normally higher than glass)
- Problems during an industrial production with the costant distribution of
the oxigen barrier along the jar/bottle profile (since it is a stretched multi-layer, the thickness of the nylon layer can not be constant along the shape of the bottle/jar and this could bring an unexpected oxigen input with a reflection on the products shelf life) - Low clarity
- High cost of production machines
- Low recyclability due to the different layer in the Coex (for example Polypropylene with EVOH or NYLON)
Advantages:
- Good clarity
- Great oxygen barrier
- Monolayer product (good recyclability)
- Low cost
- Allows to play with shapes and colors
- Unbreakable
- Possibility to have both jar/bottle and cap in plastic (mono-packaging)
- Low weight
- Possibility of “in-house” production with the relative logistic cost savings (less used storage space of the incoming preform compared with the other empty packaging) and better hot filling performance.
- Possibility to create Marketing campaing based on the good environmental friendly” aspect of this packaging compared with the others (good LCA, good “carbon foodprint”..etc..etc)
Disadvantages:
- Low heat resistance
- Possible shelf life problems with the products that want more than 24
months (to be verified with the product contained)
