Shrink Wrap Film – Presentsation Counts

Manufacturers across the divide continue to produce quality products. We are all too familiar, with the attractive transparent packaging of toys, imported fruits, clothes, pens amongst other things. Unlike the previous times, customers can still have a glimpse into their prospective purchases, carefully examining them without necessarily compromising their state or quality (food).

It is of note that, both polymers are ideal for different packaging purposes. The choice of shrink film is determined by the product, budget and level of technology the producer in question has.

The undeniable fact is, packaging being the cornerstone of branding and advertising can be responsible for high sales volume or the reverse. Manufacturers and producers alike are today faced with the tough task of choosing the ideal packaging material. In the end the functionality of the shrink wrap can only be determined by the manufactures and producers.

It is as a result of these demands that the skrink wrap film was developed. In the formative years; we were all accustomed to the brown paper bags which had our tree population on the decline. Subsequent move to the opaque store-name-christened polythene was a further disservice. Then came the perfect solution to all these problems, the shrink film.Initially, the shrink film was exclusively made from PVC (Polyvinylchloride).This is a plastic polymer (third most used plastic in the world) that had the capability of sealing products with a thin layer of plastic sheet. These sheets were often transparent to allow the customer have a view of the product.

The sheet would be wrapped over the product and passed over a heat tunnel or a heat gun. Normally, the length or circumference of the product would be measured, 10% of this value would be added then the sum is divided by two, this would give the size of PVC shrink wrapping to be used. PVC has the ability to shrink by 40% percent giving the packaging a tight grip of the product.

However, with time it was noticed that PVC could release small amounts of hydrogen chloride giving the products a characteristic smell in addition to poisoning. The sealers also would have small carbon deposits. The presence of a plasticizer in PVC had the drawback of hardening and shrinkage during cold weather and extreme stetching with subsequent temperature increases.

These drawbacks meant a suitable shrink film devoid of a plasticizer be developed. Polyolefin was found to have the packaging abilities of PVC but lacked the setbacks that faced the latter. It became a preferred choice of packaging. Offering a stronger seal and fewer odours. Its lack of plasticizer meant no physical changes to the shrink film. It would become the perfect storage solution; all weather .Lack of chlorine in its polymer meant no hydrogen chloride previously characteristic of PVC. Visit for info about film options.

However, while its predecessor PVC enjoys machine compatibility and low cost purchases, polyolefin is the opposite, it remains relatively expensive and hard to use alongside machines.PVC on the other hand remains a suitable choice for manufacturers who don’t deal with edible products. Owing to its cheap price and machine compatibility it is a manufacturers darling.

Concrete Cutting and Core Drilling Brisbane

DIY vs Hiring a Concrete Cutting Service – including a Step by Step Guide

There is a vast variety of concrete saws and equipment that can be hired to do that pesky DIY project that you have always wanted to get done. But when should you hire a professional and when should you just give it a crack? To do your concrete cutting or core drilling job properly and on budget you will need: the right equipment, the right type – wet or dry, the right protection for yourself and the environment, the right skills and the right value for money. There is lots to consider, but if you read on and follow this step by step guide we can explore this in a little more detail.

Step 1.Choose the right equipment: For gener slab cutting Brisbane you will need a Floor Saw or Kwik Cut Saw (Hand Saw). This process is used when reasonably level and flat surfaces have to be cut and includes cutting through reinforced concrete, precast concrete, and other structural materials.

These surfaces include floors, roofs, bridge decks and suspended slabs. The surfaces are usually cut to provide expansion joints, to make openings for ducts, elevators, stairwells, machine pads, trenching and for demolition purposes.

For wall sawing Brisbane you will need a Kwik Cut Saw (Hand Saw) or Ring Saw. This process is used for the cutting of openings in vertical surfaces and surfaces with slopes so great that floor saws cannot be used.

These surfaces are usually cut to provide for doors, windows, vaults, silos, chests, foundations, ducts or large diameter pipes, or to remove part or all of existing walls. For core drilling Brisbane through a floor or wall you will need a core drill. Core drills can usually drill holes from 25mm dia – 660mm dia. This process is used for the drilling of circular holes in reinforced concrete, precast concrete, asphalt, brick, cinderblock and other structural materials. Usually the holes are made for electrical, plumbing, heating, sewer and sprinkler installations. Other applications include holes to anchor bolts or lifting rods, to place explosive charges, to install load carrying devices, or for analysis of the structure of the rock.

Step 2. Wet or Dry cutting? I don’t mean to scare you here, but cutting concrete can be very messy. You can probably figure out that the dry cutting means cutting without water and should be less messy… hmm not so sure. Cutting without water means dust and lots of it. Very messy, minute particles of concrete will billow into a thick cloud of grey concrete dust or red brick dust and coat everything nearby you own. Personally I prefer the wet cutting machines. Even though the mess is wet grey or red slurry, it is much easier to clean up all the mess with a wetvac (wet and dry vacuum cleaner) and a wipe over with a damp cloth. Dust on the other hand can get absolutely everywhere.

Step 3. Protect yourself and the environment. Basic safety equipment you will need include goggles, ear plugs, safety boots/steel capped gumboots and gloves. If you have chosen a dry cutting machine you will also need to work with a dust mask on to protect your lungs, and sun protection and long sleeves if you are working outside.

Cutting concrete can be very noisy so be mindful of neighbors and nearby businesses in case of noise pollution and air pollution. Think about what is below you if you are cutting on a floor higher than ground floor. Sadly I have heard of some terrible injuries because of falling cores and no safety barriers. Protect the environment with plastic sheeting, extraction fans and a wet/dry vacuum cleaner. In many countries, letting waste such as concrete slurry go down the drain is against the law and you will be fined.

Step 4. Check if you have the right skills. There are many dangers associated with concrete cutting equipment. Even though this equipment can be readily hired, this equipment should only be operated by experienced personnel. You won’t need to google ‘saw injuries’ to imagine the dangers of operating such powerful equipment without the right know how and strength.

Step 5. Check out the cost. Believe it or not the cost to hire a skilled professional who has all the equipment needed and can get the job done with minimal fuss, is often not much more than hiring the equipment yourself. Aside from the safety risk, mistakes in concrete are expensive if you get it wrong. Before you go ahead with the hire, at least get an idea of price from a professional by obtaining a quote.

For example you may be surprised to know that at you can hire a Brisbane concrete cutting operator to do a basic job for about $150.00. That’s hardly more than the cost of hiring the concrete cutting equipment, and comes with a skilled operator to do the hard work. Might just be worth the call?

A Detailed Overview of Extruded Polystyrene Foam Insulation (XEPS)

Rigid plastic foam insulations for commercial, residential and industrial insulation can be divided into four different categories : Extruded Polystyrene (XEPS), Polyurethane (PUR), Expanded Polystyrene (EPS) and Polyisocyanurate (PIR). Every type of foam insulation has different characteristics and offers specific benefits and limitations for particular building applications.

However, Polystyrene offers some stable properties when it is combined with a distinct foam extrusion process. Thus, it is able to produce an exceptional product which is very useful. XEPS offers products that fulfill almost every kind of engineering and construction application.

Extruded Polystyrene (XEPS) has always been popular for superior resistance and long-term reliability to numerous fundamental forces of nature, including water, heat, time, pressure and cold. While choosing insulation types, you need to consider all these forces.

A Brief Overview of the Extrusion Process
Extruded Polystyrene foam generally begins with just solid polystyrene crystals. These crystals are mixed with a blowing agent and special additives before being fed into an extruder. Once the mixture is fed into the extruder, it is combined and melted into a viscous plastic fluid. All this happens under controlled conditions of high pressure and temperature.

The molten thick, hot liquid is forced in a continuous process with help from a die. As the hot liquid emerges from the die and expands to a foam, it is cooled, trimmed and shaped to dimension. This is a continuous extrusion process which results in a unique foam product with a perfectly uniform closed-cell structure. It also offers consistent product qualities, smooth continuous skin and other qualities which may not be matched by other insulation types.

In simple words, all the qualities and benefits offered by extruded polystyrene are almost impossible to duplicate in any other type of insulation. The qualities possessed by XEPS make it very well-suited for formation into stackable blocks and panels to serve the basic purpose of wall insulation into homes.

XEPS foam can be easily cut for electrical wiring. It can easily run through or near it. These interlocking XEPS interlocking foam formations are usually manufactured with hollow regions. These regions can be filled with concrete to create a grid of beams and columns when dry.

Other Beneficial Properties of Extruded Polystyrene

Here are some benefits of XEPS :

Chemical Resistance – XEPS is considered and recognized as the most stable polystyrene foam insulation. It is tested and verified to be resistant to various common chemicals like bases, acids, water, alcohol, water-based paints, alcohol-based paints, salt water or brine, mortars, cement, asphalt and so on.

However, it is worth mentioning that petroleum-based products can still attack this type of foam insulation. Therefore, you should avoid foam contact with high concentrations of solvents like chlorinated hydrocarbons, aromatic hydrocarbons, fuel oil, gasoline, naphthas, cut-back asphalts, paint thinner, oil-based insecticides, oil-based paint, polyester resins, wood preservatives and so on.

Soil Compatibility – Such foam insulation is unaffected by most of the substances found in soil, including alkalis, acids, bacteria and so on. XEPS foam insulation does not rot, corrode or support growth of mildew, mold and soil microorganisms. It neither offers any food value nor supports animal or plant life. You need to take certain precautions when this type of insulation is in contact with the soil. It will help you prevent any sort of hidden entry through the foam by insect pests or vermin.

Storage & Outdoor Exposure – XEPS foam insulation is not affected by extreme weather conditions. Therefore, it can be easily stored outside. However, prolonged exposure to UV rays in strong sunlight can cause the surface to become dusty and pale. But this will not have any significant effect on insulating value unless the surface’s thickness is reduced or eroded. You can simply brush off surface dust before applying finishes or adhesives. If you plan to use this type of insulation outside for a long period, you can even use an opaque protective covering.

It is important to understand that extruded polystyrene can be quite expensive. In fact, it can easily add around 5%-10% to the cost of building a house. However, you will be able to save a lot of money on cooling and heating. This will help you recover the extra cost over the life of the structure. It is clear that XEPS foam insulation offers numerous benefits and proves to be the best type of foam insulation.
