Performance evaluation of new plasticizers for stretch PVC films
Polyvinyl chloride (PVC) Film Stretch Plasticizer Packaging abstract Six stretch PVC lms have been formulated to have Shore A hardness of approx. 80 and nominal thickness of 15 mm with the aim of evaluating the performance of plasticizers from renewable and non-renewable sources for stretch PVC lms intended to be employed as packaging.

Performance assessment of polyvinyl chloride films
PVC films were tested for the determination of migration stability of plasticizer in different solvents for 72 h and obtained results are represented in Fig. S9. PVC film plasticized with DOP (PVC A) exhibits maximum migration in each of the solvent. The migration is decreased as the concentration of ECLO is increased.

- 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.
- 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 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 stretch PVC films transparent?
- Samples 2, 3, 5 and 6 showed high transparency (%T approx. 90%) both in the UV region (wavelength lower than 380 nm) and visible region (wavelength higher than 380 nm). Fig. 2. Regular light transmission spectra of stretch PVC films with different plasticizer types. However, samples 1 and 4 showed lower light transmission below 300 nm.
- Which raw materials are used to make PVC plasticizers?
- Examples of raw materials used are numerous, such as corn, soybean, sunflower, palm, castor bean and flaxseed, among others. Usually, the processes of transesterification, alkylation and epoxidation are used to manufacture these potential PVC plasticizers. The results have been quite promising and some markets are already trying and using them.
