Evaporation Resource By Preventing Evaporation 70% of the potential heat loss can be prevented Why? &Heatloss To heat 1 gram of water = 1 calorie of energy To evaporate 1 gram of water = 540 calories of energy 1 calorie is = 4.186 joules the specific heat of water. This is how a solar blanket is able to heat the pool so effectively compared to a uncovered pool gram for gram the energy savings are vast. This is also why sweating cools you down! All Plastipack materials have been independently tested and reduce evaporation by over 98% 31/10/2013Copy Right Plastipack 20133
Insulation The air trap inside and between the bubbles work as insulation and condensation between the bubble make the material near opaque to radiative heat responsible for 20% of the heat lost in a pool. keeping the pool warmer at night giving a head start in the morning. 400 micron Light Blue material. Thermal information in different formats, R, U and K values The R value for Plastipack’s 400 Grade products is 0.06 m²K/W. The overall thermal conductance or U value is = 1, which is 16.67 R W/(m 2 K) for Plastipack’s 400 grade material From this a k value (Thermal conductivity) can also be worked out, when R value is known = Thi c kn es s in m etres Thermal conductivity (k) So k value is 0.00606 (W/K-m) for Plastipack’s 400 grade material. 31/10/2013Copy Right Plastipack 20134
Keep DebrisoutofthePool Keeping the cover on not only keeps the heat in the pool but also prevents foreign matter from entering the pool. Only 10% of the chlorine in a pool is used as the active sanitizer to keep the water safe the other 90% is used as an oxidiser to break down foreign matter in the water added bathing loads. bydebrisblowing in and 31/10/2013Copy Right Plastipack 20135
Understanding Chemicals can increase the life of a cover Please see pool cover diagnose A important emphasis is placed on the material being kept to industry standards and to be removed when shock dosing: Chemical Balance Summary SubstanceIdeal Range Salt Stabiliser Free Chlorine Combined Chlorine Total Chlorine Total bromine Ph Total Alkalinity Calcium Hardness Total Dissolved solids Phosphate Heavy Metals 2500-4000ppm depends on chlorine demand 2.0-4.0ppm <0.2ppm TC=FC+CC 4.0-6.0 7.2 -7.8ph 80-120ppm 150 -400ppm <2000ppm as little as possible * Note a cover dose not need to look degraded for the damage to have already been do for more information please see cover diagnoses) *ppm (part per million) 31/10/2013Copy Right Plastipack 20136
The GeoBubble™ is a new technology of bubble designed specifically for the swimming pool environment. For many years the standard packaging bubble design has been commonly used in the market. However, this design was not created to be a product with any considerable longevity, in fact its design function is the complete opposite. The creationof a bubble design which is more resistant to the environmental stress placed on the cover material was the goal of the GeoBubble™ design.
Bubbledesign Bellow is a example of vacuum forming the method used to make the bubble shape. As shown the material thins as it is drawn into the mould. The thinnest point will be the last place to come into contact with the mould This Produces weak points in areas of high residual stress (sharp corners) and which undergo chemical attack which will result in these areas degrading faster.
Residual stress:are stresses that remain in a moulded plastic material after the original cause of the stresses (the forming has been removed. and extrusion process) Rounded shape minimises stressesSharpe angles create areas frozen in stress This is why most Plastic products are rounded and shape corners avoided when ever possible Stress crack will appear Failure point will occur
A Structural arch prevents bubble collapse and resists air expansion Rounded Shape Removes residual Stress making the material 50% thicker at its thinnest point Peanut Shape provides a stronger more ridged profile with greater room for air expansion

LaminatedWeaves Plastipack provide a laminated woven material this consists of a 200μm, UV stabilised, HDPE flat woven mesh sandwiched between two thin films of LDPE. This woven material is heat bonded to the top surface of the bubble material on our production line creating a permanent bond between the woven sheet and the bubble material. Our blue pigmented woven material called Polyweave comes in 2m and 2.5m widths. We also supply a clear woven for application where heat gain is required called Solarweave available in 2m. The woven material provides tensile strength making a more durable material. Besides this benefit the only difference is in the materials weight a standard 400μm material ways 368gm² with the weave laminated to the material this will increase to 540gm². When welding the woven material using a hot wedge welder Plastipack recommend through there own experience running the welder at 490°C at a line speed of 90 (9 on new models Phaffs) using a gripping roller for the best possible weld.

Reflective cover sheet Storing the cover on a reel can cause the material to deform to the shape of the reel when left in direct sunlight. To solve this issue Plastipack developed the reflective cover to allow ease of storage when not in use. The material deforms as the insulating properties of the cover causes heat to builds between the layers which can reach harmful level. By protecting the cover with a the reflective cover material the internal temperature of the material can be reduce by up to 30°C. 31/10/2013Copy Right Plastipack 201327
