Pelliconi keeps the Food and Beverage industry moving with SoPure®: the new PVC-Free Jar Lids

Annabella Cusati - Dec 9, 2020 2:36:29 PM

Everyone in the baby food sector knows the great reliability of PVC as a sealant for the food containers. However, it contains additives that can contaminate foods, especially those with high fat content. In this case, we are in the presence of what is called "migration" in technical jargon.

This transfer of chemical contaminants, potentially harmful to our health, occurs because plastic additives are added to the base polymer of the sealing material to optimize the seal’s performance.

For this reason, Pelliconi has created SoPure®, a closure suitable for glass containers that is easily recyclable and PVC-free. This new idea supports the orientation of large producers of baby food which, in response to a growing awareness of ecological issues and social responsibility, are moving towards the elimination of polyvinyl chloride as well as other materials that can be harmful to people and the environment.

Customer – Background – Challenge – Solution

In this current scenario in which the consumer has developed a greater awareness of what they buy, especially if it concerns their children’s nutrition, and a strong sensitivity towards ecological issues, the baby food multinationals are increasingly adopting a policy based on transparency and safety. This has translated into greater use of eco-sustainable packaging and safe and traceable raw materials.

An example of this is Plasmon, which, in collaboration with the Italian government (Mipaaf), last May, guaranteed purchases for 25 thousand tons of agri-food products from national supply chains to promote its brand reputation, focusing on safe and sourced foods that are verifiable. 

The trend recorded recently is related to the aspect of quality. Therefore, it is an all-encompassing value, which is not only reflected in the choice of the food itself but also in the type of trust relationship that is established between the producer and final consumer, which also concerns every characteristic of the product.

In fact, the latter prefers a direct relationship with companies, greater transparency, and ease of communication, which must be informative and complete.

The trend towards transparency and social responsibility is also affecting online sales channels, which in the current context, have registered exponential growth, even in the consumer goods sector (and, as a result, in the baby food sector).

Growing Sustainability trend

Nielsen, global market measurement firm, estimates that in 2022, e-commerce sales of consumer goods will reach a value of 400 billion dollars, with Asia leading the way.

In line with the green trend of the consumer goods sector, the increase in "virtual" sales has generated the request to reduce excess packaging, especially in the case of large multinationals such as Amazon, which is reconsidering its packaging usage policy.

The tendency to produce more eco-friendly packaging solutions based on bioplastic materials.

All this is done without giving up the "identity" aspect of packaging, which has always been one of the essential cornerstones for helping a brand stand out from the competition.

Environmentally friendly alternatives to PVC helps provide product differentiation

The orientation towards green packaging is confirmed by all the experts’ forecasts, which point to an annual growth of 7.7% until 2025, the year in which the market value will be around 440 billion dollars.

Other extremely important data emerges from the European Consumer Packaging Perceptions Study published in 2018: media coverage on packaging waste has influenced the purchasing habits of 74% of Europeans.

This is accompanied by another equally important fact: 69% of European consumers said that making positive decisions that protect natural resources is more important than in the previous five years.

A virtuous example of ecological sensitivity is that of Be Green Packaging, a company at the forefront in terms of solutions capable of making a difference in the market. They have developed a type of packaging in renewable natural fibers, usable in the most disparate sectors, including food.

Another brand that has begun reducing packaging is Marks & Spencer, which specializes in selling food products and clothing. In fact, with Project thin air, they have considerably reduced the volumes of plastic (75 tons of packaging materials saved in a year) by decreasing the size of popular snack bags such as chips and popcorn, while keeping the same amount of food inside.

In the same way, Pelliconi's commitment to support green policies such as those just described has always been a real trademark.

This can be deduced from the creative effort in creating SoPure®, a PVC-free closure, equally performing in preserving food but with significantly better behaviour in terms of migration and safety.

Therefore, it is a solution that perfectly matches the idea of differentiation implemented by the baby food multinationals and pushes the entire sector to innovate.


With SoPure®, Pelliconi has created an innovative product for this sector, without imposing any changes on the production line of the companies that embrace it.


Pelliconi presents a new technology for sealing baby food jars: SoPure®

SoPure® is an original solution because it is a capsule free of plasticizers such as phthalatesused to make PVC flexible—and made with Provalin®, a compound produced by Actega.

Migrational properties of Provalin® for SoPure®

Provalin® is a blend of thermoplastic elastomers (TPE) composed by more than 95% polymer and less than 5%  lubricants and stabilizers.

On the other hand, the PVC compound has a percentage of liquid plasticizers not linked to polyvinyl chloride; therefore, it is potentially able to migrate into food, which varies between 35 and 40%.

This is a very high threshold, considering the European standards on the subject, which set a maximum allowed overall migration limit of 60 mg per kg of product.

Studies on 51 mm caps for 80 ml glass jars have shown that, Provalin®’s global migration remains below 60 mg/Kg over 12 months, while, PVC increases exponentially over time to reach 140 mg/Kg or more

Provalin® PVC-free, also  received important recognitions   for its ability to be abundantly maintained under the migration threshold, as well as stable during a one-year time window.

This excellent peculiarity allowed Provalin®, in addition to having been adopted by Western companies active in the food industry, to conquer significant market shares also in Asia.

In fact, the product has all the requisites suited to the stringent Asian anti-PVC directives, lending itself optimally to the closure of highly oily foods such as pesto or mayonnaise.SoPure intern

Why PVC-free is the best choice

  • Does not contain phthalates and adipates, substances that can be harmful
  • No migrations of additives like plasticizers into food
  • Allows a much easier disposal process and makes it suitable for both metal recyclability or incineration.
  • Compound production has a lower impact on the environment
  • If burned in an incinerator, it does not release toxic gases like dioxins in the atmosphere


The advantages of SoPure® capsules

  • Suitable for types of jars subjected to thermal stress as in the case of pasteurization and sterilization processes
  • Suitable for the long-term storage of baby food, sauces, and other foods
  • It can be capped using the standard production line for glass containers, therefore, without further economic investment to convert production
  • The disposal has a lower impact on the environment largely respects the migration parameters provided by all legislations;

Thanks to its green and safety specifications for your health, SoPure® allows companies in the sector to differentiate themselves and be proactive to change.
