Decovery® SP-6000 XP

All the performance, with less of the oil – and repulpable

Decovery® SP-6000XP is a barrier coating resin, which is an alternative to PE and PFAS based solution. This high-performance 29% bio-based acrylic is designed for barrier coatings for paper substrates. It works very well with all existing application methods, especially flexo and gravure. Decovery® SP-6000XP resin provides water barrier (Cobb) combined with highly flexibility. It performs well in flexible paper substrates in food and non-food applications such as sandwich wraps, tea envelope, folding board boxes and other take away packaging.​

The flexibility your packaging needs

Decovery® SP-6000XP’s water barrier properties (Cobb-tested) prove its grease resistance in highly flexible performance. This makes it especially effective when used in flexible paper substrates for food and non-food applications, such as sandwich wraps, tea bag, folding board boxes and other takeaway packaging.

Putting Decovery® SP-6000 XP to the test

Ensuring good grease resistance (Kit and grease test)

The purpose of this test is to ensure any food packaging retains grease and oil while preventing contamination of the product.

Grease leakage will eventually cause dark spots on the outer layer of the paper or board. 

In the Kit test, a drop of fluid is put on the side of the board. The time it takes for spots to appear on the board is then measured, and expressed as a measurement of a material’s grease resistance.

In the grease resistance test, a cup of olive oil is poured into a folded substrate. The time it takes for oil to start leaking through the substrate is then measured.

Testing for Coefficient of friction

Coefficient of friction (COF) is critical to the optimum processing and handling of packaging. There are two common basic COF testers — sliding plane and incline plane.

There are two measures used to establish overall COF:

Static COF – measured the very moment motion starts between two surfaces,

Kinetic COF – this is established once motion between two surfaces commences

Why is this important? If either of these values is too high, this can cause problems throughout the printing process, such as obstructions in the filling line and issues with stacking printed materials.

When either is too low, materials (such a paper or film) may not pass easily through machines or machinery may run too slowly to actually process the materials.

According to recent customer feedback, our excellent COF scores reassure them that our products provide an excellent starting point for their formulation.

To ensure our resins help prevent water uptake by the substrate

The Cobb test determines the amount of water that is taken up by an area of paper or card by placing one side of the substrate in contact with water for a defined period of time.

A high Cobb value shows that the substrate has a good ability to absorb and retain water. However, a low Cobb value tells us that the substrate is able to resist water.

The low Cobb scores that Decovery® SP-6000 achieves means it will protect your paper and board from water uptake, outperforming the starch alternatives in the market.

To ensure an effective seal

We test the following properties:

Seal limit

The minimum temperature needed for a proper seal at given times and pressures. Normally expressed in °C and may refer to the machinery used in the test e.g. Otto Brugger.

Seal window

The maximum and minimum temperatures between which proper seals can be formed on packaging. They often refer to the running speed of the film on production line.. You may also see seal windows described in terms of branded machinery.

Seal strength

The maximum force needed to tear a specified width of a seal. Expressed as force per width e.g. N/25mm.

Decovery® SP-6000 XP is tested extensively to meet market sealability requirements.

Why we also run anti-blocking tests

When packaging is stacked for a long time, ink components can detach from the printed surface when the stock is separated.​​

This can also occur when substances used in printing inks transfer from the printed surface to the inner, food-contact surface.​​

Our blocking test calculates the overall effectiveness of a coating when stacked or compressed against other printed items.​​

In tests, our coating resins did not stick to the neighbouring packaging, matching (and even exceeding) the performance of many fossil and bio-based materials in the market.
