Packaging

Refrigerated Food

Top Image

One of the greatest challenges in food packaging today is the preservation of refrigerated products. Now more than ever, customers want the convenience of having an assortment of healthy, fiber-rich, garden-fresh produce instantly available in their refrigerator to feed their families.

At Tosaf, we understand that different food types have different requirements. Fresh produce, for example, needs to look fresh, with no signs of browning, limpness or deterioration in quality. Dairy products require special environmental conditions and packaging that keeps them safe for consumption.

Working with you, we apply our expert knowledge, innovative ideas and technological knowhow to developing unique additives for different packaging applications, so that you can impress your customers and increase your sales.

HIGHLIGHTS

Anti-fog

Packaging for refrigerated food products with high humidity ratios is prone to contain condensation. This limits product visibility, and may put off customers who won’t buy what they can’t see. With 15 years of experience in developing and producing high-quality anti-fog additives, we can help you design and produce packaging with superior anti-fog properties, for any application.

Processing Aid

The appearance of packaging can have a big impact on whether or not a customer chooses to buy a product. But it can be difficult to achieve stable, defect-free film production at high outputs and when using polymers with specialized properties. Our high-quality processing aid solves this problem, enabling you to improve the quality of your film, while reducing energy consumption during production.

Our Products

UV

Polyolefins are sensitive to UV light, which can cause significant damage to plastics. Each polymer has a different minimal absorption peak in the UV range, and its expected life will depend on the irradiation level to which it is exposed, its thickness and the additives it contains. We have developed an innovative range of additives that help to protect products made from polyolefin from light and heat degradation. Sharing with you our knowhow and years of experience, we will advise on which additives to use, how to use them and in what quantities, to optimize them for both your production process and the final application by the end user.

AF (Anti-Fog)

Our anti-fog masterbatches contain innovative additives that migrate to the surface of the film, reducing the surface tension with the water so that, instead of drops, the water forms a thin, uniform layer that does not obscure visibility. As a result, you get excellent optical properties and better product appearance, along with first-rate processing to minimize die buildup and maximize productivity.

AF Barrier

Awareness of the importance of AF function in refrigerated food has increased in recent years. At the same time, the films have become more complex and sophisticated. Usually an additional process is required, such as printing or lamination. Due to the fact that AF is a migratory additive, there is a need to find a solution in which the migration will not negatively affect the converting processes on the one hand, and AF function will be perfect on the other. With our knowhow in the field of materials and market needs, we have developed a unique additive that allows film manufacturers to run converting processes without any fear of delamination or weak color grip, while maintaining high-quality, lasting AF performance.

Slip

Slip additives make film production easier, by preventing layers of film sticking together, or sliding over each other. However, they must be used with caution. Too much slip agent can cause blooming - reducing transparency, negatively affecting the printing and slipping properties of the film and increasing the risk of low bonding strength on laminated structures. You also need to ensure that the thermal stability of the slip additives used is suitable for the relevant film process conditions. With over 20 years of experience, we can help you avoid these issues.

Anti-Block

Polyolefin film tends to stick together when an attempt is made to separate it into two film layers. This so-called ‘blocking’ is determined by the composition and rolling tension of the film. The quantity and type of anti-blocking agent incorporated into the film to solve this issue can affect transparency, or it can adsorb migrating agents, such as anti-static, slip, or anti-fog additives, decreasing their efficiency. Using our experience, knowhow and synthetic silica (rather than the more commonly used crystalline natural), we can help you avoid these problems.

Slip-Anti-Block

We offer you the advantage of both slip and anti-block additives in one masterbatch, so you can avoid significant adsorption of the migrating slip additives by the anti-block agents. Our range includes several grades suitable for different types of packaging processes, so you get an innovative, agile additive that meets several needs at once.

Anti-Static

Polyolefin materials are not conductive, so they accumulate static electricity which can cause films to stick to each other or other surfaces, pick up of dust, and even sudden discharge as sparks, causing fires. Our anti-static masterbatches contain migrating molecules which migrate to the surface and attract a thin layer of water molecules from the air, which is sufficiently conductive to dissipate the charge. Our wide range of masterbatches meets different needs, making them suitable for use in a variety of relative humidity levels, from dry to high moisture.

The appearance of packaging can have a large impact on whether or not a customer chooses to buy a product. But at high outputs and when using polymers with specialized properties, it can be difficult to achieve stable, defect-free film production. Our high-quality processing aid solves this problem, enabling you to improve the quality of your film, while reducing energy consumption during production. Our extensive range of Polymer Process Aid (PPA) masterbatches have been specifically designed to enhance the process ability of plastics, such as PE film, pipes and tubes, to improve productivity and quality, and reduce costs.
