For the fabricator:

What dimensions is the material available in?

Plastipack supplies material in widths of 2 and 2.5 meter lengths, on rolls of 51 to 102 meters long, with a 30mm weld edge.
Our welded material is supplied on Jumbo rolls in widths of 4 to 6 meters, on rolls of 51 meters long.

What are the minimum order quantities?

For non-stock products, our minimum order is 60 rolls at 51meters long, or 30 rolls at 102 meters long. This represents one production run on our manufacturing line.

How is the material welded?

The most common welding methods used are hot wedge welding or ultra-sonic welding. For more details, please see our Welding Guide or contact us with your specific question.

What countries does Plastipack ship to?

Plastipack is a global distributor. Contact us directly about becoming a Plastipack customer and join our growing international network.


Installation / trimming:

Does the material need a hem around its edge?

No, the use of hems is purely an aesthetic choice. A pool cover without a hem performs in exactly the same way as a hemmed cover does.

What is the best way to store the material?

We recommend storing all stock material standing upright/on one end in cool conditions and away from direct sunlight. This ensures the most effective use of storage/warehousing space and prevents any damage to the material.

Does the material shrink?

Our material has a 2% shrinkage rate in length. This is due to the nature of the polymer used in the manufacturing of the material. When shaping the final pool cover, it is important to take this into account by adding 2% to the length of the material to ensure a good fit once the cover has settled.

Is Plastipack’s material recyclable?

Plastipack’s material is a blended LLDPE, LDPE mix. As such, it is classified as LDPE 4 recyclable material. This mark can be found on the material’s weld edge and should be recycled accordingly.


Cover types and performance:

What is the difference between a Guard product and ‘Standard’ materials?

The key differences between Guard and Standard materials are in covers lifespan and performance once the cover is fitted. Our Guard products have been designed and independently tested to ensure the product pays for itself in chemical and energy savings within one year. The Guard range has a tailored stabilizer package which allows a lifespan of up to six years. Providing a significant increase in the products useful life compared to a standard materials 2 to 3 year life span.

What effect does colour have on the cover’s performance?

A pool with an opaque cover uses less chemicals than one covered with a translucent material. The reason for this is two-fold. Firstly, algae require light for photosynthesis. Without light, its propagation is prohibited reducing the chemicals need to oxidise the organic matter, leaving it free to continue to sanitise the pool. Secondly, when chlorine is exposed to UV rays/sunlight it dissipates and is deactivated in the photolysis process. A opaque cover shields the pool preventing the chemicals from being deactivated.

In terms of providing free solar heat to the pool the best option is a material with a high transmittance, allowing solar gain to heat the pool evenly. Dark / opaque materials which absorb the light and re-emit this energy as heat to the surface of the pool will help raise the pool’s temperature. However, water is an excellent absorber of heat (IR light) which means this heat will be retained within the top surface of the pool only. A translucent material can heat the water evenly and more efficiently resulting in greater temperature gains.

If you wish to keep the pool cool, an opaque material with a high reflective index is needed to shade the pool and reflect away the suns energy keeping the pool water at a comfortable swimming temperature.

When should the cover be placed on the pool?

For optimum savings on water, power, and chemical consumption, a swimming pool cover should only be removed when the pool is actually in use. Always re-cover the pool immediately after use. You’d be surprised at how quickly water and heat are lost!

How do I select the right material for the pool?

First of all, it is critical to have a clear understanding of the pool owner’s daily habits and how the pool is used year-round.

If the user’s key concern is heating, opt for a clear cover to allow as much light through as possible, for example, Sol+Guard.

If chemical consumption is of concern, or if it is a pool that is seldom used, an opaque material is the best choice, for example EnergyGuard ST. This will save on chemicals and allow for a chemical- and filtration-free shut down or hibernation period without an outbreak of algae.

In a warm, tropical climate where the pool owner wants the water kept refreshing enough to swim in, opt for a highly reflective cover such as CoolGuard. This material reflects the heat, cools the water and maintains the water at a comfortable swimming temperature.

All the above mentioned covers have a range of other benefits. Visit our Products page or download the brochures here.

What are the recommended chemical levels for a well-balanced swimming pool?

Follow the chemical level guidelines below to maintain a healthy pool and achieve the maximum cover lifespan. When shock dosing (super chlorinating) the swimming pool, or if the pool goes out of balance, always remove the cover from the pool to prevent excessive chemical degradation.

Chemical Levels

How many years’ use will I get out of my pool cover?

Different additive packages and material thickness can affect a product’s lifespan. Research and development are key to longevity, making this a core focus area for Plastipack. We continuously test existing products and develop improved materials that allow for a longer lifespans and therefore add value for money for both the fabricator and the end user.

The following expected lifespans have been ascertained by testing our products on control / test pools with chemical levels that are consistent with the recommended industry standards.

Lifespan

Products using the GeoBubble™ technology have a 25% longer lifespan than the Standard products.

Why is the reflective covering important to use?

When off the pool and left in direct sunlight, heat quickly builds between the layers of material. Once the material reaches its Vicat softening point, the material goes into its rubbery phase. If left to cool in this position, it will set to this new shape. To prevent this, the reflective cover is an opaque sheet shades the cover until it’s ready to go back on the pool.
