DAIRY. Definitive light barrier with monolayer PET bottles
1. UHT milk
2. ESL milk
3. Milk based drinks, cream, yogurts, soy milk, etc.
A proven
PET solution for long
shelf-life dairy products
The polymer solution. The right choice and the real newness
Bad pigment dispersion with master batches
FAM 2006048G: Novapet, Spain
Bottle B-1. Pigments' content: 8%.Cross-section, etched
Competition (master batch)
Perfect dispersion with Dairy polymers
FAM 2006048H: Novapet, Spain
Bottle B-2. Pigments' content: 8% Cross-section, etched
Advantage 1. Better light barrier
Better light barrier with a lower overall
content of pigments.
Longer product shelf-life
Advantage 2. Better mechanical performance
Better bottle strenght with lower wheight.
Advantage 3. Better organoleptic guarantees
Minimal alteration of virgin PET, leading to lower degradation of the material and, thus, to better preservation of flavours and odours.
Advantage 4. Better processing, better quality, fully comparable with conventional PET.
- Solution fully integrated in the polymer, which requires no additional equipment or additional operation for addition pigments, colours or filters. Clean processing with no waste. No adjustment necessary in start-up.
- Very high stretching ratios for material, which leads to great versatility in Dairy preforms .
- Standard drying conditions.
- Totally conventional injection. Cycles fully comparable to those of the same preform injected with PET standard.
- Blow-moulding adaptable to maximum machine speed, with no type of penalty.
- Totally conventional quality rates. Constant light barrier in every bottle. Constant weight. No delaminating. No bottle burst.
Advantage 5. Better overall costs
- Reduced investment. Injection mould versatility.
- Consistent and reliable quality.
- Optimization of pigment use.
- Constant preform weight.
- Quick and easy production changes.
- No bottle breakage.
- Better mechanical performance of the bottle, leading to optimized weights.
A new Dairy resin, resulting from an innovating combination of pigments, making it possible for the first time, to obtain monolayer bottles with virtually a full level of screen.
