rPET Resin (Food Grade)
Product Features
- PET’s performance advantage of lightness, strength, unbreakable, barrier properties, clarity and simple to transport have all been exploited to replace glass and PVC in the manufacture of blown bottles and custom containers.
- Soft drinks( CSD) were the key drivers in this acceptance, followed by mineral water as PET bottles provide better packaging at a lower cost than glass bottles
- Growing number of food, household and personal product application adopted PET as product of preference.
- In thermoformed sheet sector PET continues to replace other polymers such as PVC, Polystyrene for packaging applications.
- PET bottles are a tenth the weight of an equivalent glass pack. Thus, PET bottles reduce shipping costs, and because the wall material is thinner, shelf-utilization is 25% higher than glass. High-strength, low-weight PET bottles can be stacked as high as glass.
- The low permeability of PET to oxygen, carbon dioxide and water protects the integrity of products, resulting in a good shelf life. Soft drinks( CSD) were the key drivers in this acceptance, followed by mineral water as PET bottles provide better packaging at a lower cost than glass bottles.
- Shelf life issues of oxygen ingress, CO2 retention and UV absorption have been overcome through special coatings in bottles.
- 100% recyclability hence labelled as green and environment friendly product. PET bottles are a tenth the weight of an equivalent glass pack. Thus, PET bottles reduce shipping costs, and because the wall material is thinner, shelf-utilization is 25% higher than glass. High-strength, low-weight PET bottles can be stacked as high as glass.
- PCR is hot topic which brand owners insisted to have certain percentage of PCR in PET.
- r-PET emerges as an answer to environmental concern as recycling of PET bottles ensures material lands back in shape of bottles on shelves. The technology available makes the task easier as risk of contamination is eliminated by processing of bottle flakes through established and approved process.
- r-PET replaces PTA & MEG raw materials for PET resin and also leads to saving on account of carbon foot print.
Characteristics of rPET
- It is an internationally approved material for use in foodstuffs;
- It allows minimizing the use of drinking water for washing containers;
- Its production is clean and low in power consumption;
- Manufacturing a package requires few material, thus reducing the amount of waste;
- It allows optimizing transport logistics and distribution, thus decreasing its environmental emissions;
- It has great versatility and its chemical composition is simple;
- PET packaging is of great help in situations of natural disasters given its isolating properties;
- It is 100% recyclable
