Performance evaluation of new plasticizers for stretch PVC
Abstract. Six stretch PVC films have been formulated to have Shore A hardness of approx. 80 and nominal thickness of 15 μm with the aim of evaluating the performance of plasticizers from renewable and non-renewable sources for stretch PVC films intended to be employed as packaging. The reference film was produced with DEHA and ESBO, while the

- Can stretch PVC films be used as packaging?
- Six stretch PVC films have been formulated to have Shore A hardness of approx. 80 and nominal thickness of 15 μm with the aim of evaluating the performance of plasticizers from renewable and non-renewable sources for stretch PVC films intended to be employed as packaging.
- Which plasticizers are used in stretch PVC films?
- Considering the tensile properties, all samples will probably show adequate performance when used as stretch PVC films with slight differences between them as follows: The plasticizers ATBC, DEHT and polyadipate showed lower plasticization efficiency than the others since samples 2, 4 and 6 showed the highest tensile strength values.
- What are PVC plasticizers?
- These films have a large amount of additives (plasticizers). There are around three hundred chemical substances that may be used as PVC plasticizers and approximately one hundred which are of commercial importance. Of these commercially important primary plasticizers, esters are the most commonly known and used.
- Are vegetable oil based plasticizers better?
- The vegetable oil-based plasticizers showed better mechanical performance (values similar/near to DEHA) than the other plasticizers evaluated. The infrared spectra of PVC films can indicate the class of plasticizer used in the formulation as well as the strength of the plasticizer-PVC interactions.
- What is a sample 6 of a PVC plasticizer?
- Sample 6: band at 1734 cm −1, 1255 cm −1, 1177 cm −1 and 1084 cm −1 due to C O, aliphatic ester and C H vibration modes. The carbonyl group absorption frequencies of the ester plasticizers can be shifted to frequencies several wave numbers lower (lower energy) when the ester group interacts with the PVC .
- Do plasticizers interact with PVC resin?
- This band shift was observed for samples 3 and 5 (displacement of 4 cm −1 lower), indicating higher interaction between the plasticizers and the PVC resin than samples 2, 4 and 6 (shift of 4 cm −1 higher) as shown in Fig. 1.
