Shelf-Stable Food

Top Image

Food products on shop shelves need to maintain their quality for months, or even years. The innovative additives in our packaging solutions for shelf-stable foods provide reliable protection from moisture, oxygen and UV light, all of which can cause deterioration or spoilage, for a wide range of applications. The result is a long shelf life throughout which the flavors, aromas and appearance of the food are preserved, ensuring that the product remains attractive to consumers.

Our familiarity with market needs and evolving trends enables us to offer creative solutions in the design field, such as a matte finish, and creative packaging solutions, such as permanent slip.

 

HIGHLIGHTS

Oxygen Barrier

Oxygen causes food deterioration, so it is important that the packaging used has oxygen barrier properties. But creating flexible packaging with an oxygen barrier often requires high-end multilayer equipment that may not be available to packaging film producers. That’s why we have developed a unique solution that enables even producers of simple film to introduce oxygen barrier properties to their film.

Humidity Absorber

Without the right packaging, shelf-stable products are vulnerable to humidity. The physical barrier of the film does not always provide sufficient protection – often additional moisture absorption is required, both within and outside the package. Our innovative moisture-absorbing masterbatches are a fast-working, long-lasting solution.

Matte finish

As polymers have become increasingly available for use in a wide range of low-cost applications, the glossy sheen of their finish has come to be associated with budget products. A matte finish, on the other hand, is perceived to be a sign of quality. Our newly developed matte finish additive gives matte properties to PE films, and can be used in a range of different production applications.

Our Products

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.

Antioxidant

Oxidation during extrusion can be avoided by incorporating a secondary antioxidant material, usually phosphates. Long-term aging at temperatures below melting point can be avoided by incorporating primary antioxidant, such as hindered phenols. Thanks to a game-changing additive that we have developed, we can avoid the chemical reaction that inhibits oxidation and degrades polymer chains. Taking into account steps in the extrusion process that can partially consume the added antioxidants, we can create a film recipe to ensure that there is enough antioxidant additive to last for the useful life of the film.

Oxygen Barrier

Controlling gas diffusion has become a standard requirement of the food packaging industry. There are several ways to achieve this, such as through oxygen permeability, including coating, metallization and coex barrier, or by producing coex barrier film. Not all film producers have the in-house expertise required to achieve this. But, our powerful oxygen barriers are capable of providing an OTR of 20 cc/m2-day at a thickness of 10 microns, and can be recycled into your own layer, post-drying.

Processing Aid

Our extensive range of Polymer Process Aid (PPA) masterbatches have been specifically designed to enhance the processability of plastics, such as PE film, pipes and tubes, to improve productivity and quality, and reduce costs.
