Shrink Wrap Film – Retailers Love It

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 as a result of these demands that the shrink 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.

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.

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.

Metal Fabrication – History and Use in Mining Industry

Metal fabrication began in the earliest civilizations when the metals gold, mercury, silver, tin, iron, lead, and copper were discovered. These metals were worked by early artisans into decorative pieces, religious iconography, and jewelry. Items of a practical nature were forged from metal including coinage, tools, and weapons. Using heat and tools, metalworkers began to make functional objects and the industry developed through the years advancing and gaining value from society.

As an industrialised society, the world cannot live without metal; it is essential to almost every industry from mining and heavy industry to agriculture and medical equipment.

Specialist engineers and manufacturers fabricate metal and metal alloys, which are made from a combination of different metals for a staggering number of uses. The pivotal role of metal has been responsible for significant advances in technology, construction, transport, and agri-science. Metal has strength; it is very low maintenance and will last a lifetime and more. Specialist metal fabrication companies are made up of a group of skilled people who all have a role in the process of turning metal into supports for a building, heavy duty mining equipment or boilers and tanks to name a few.

Metal fabrication is a series of processes used to manufacture an object from metal. The specialised equipment involved includes laser cutting machinery, turret punches, machine centers, rollers, welding machinery, water jets, and metal shears. The metals most commonly used for fabrication are aluminium, stainless steel, and carbon steel, which is in the form of sheets, tubing and bars. Most metal objects start life as sheet metal in varying thicknesses depending on the application. Thicker sheets are known as metal plate.

The process starts with the design and then the fabrication begins with the metal sheet being sheared, laser cut or punched into shapes. Once the required basic shape is achieved, the object goes next to the press brake machine to form any bends a process known as forming. Dies are used in the press brake to make the correct accurate shape according to the design plans. The product may be finished at this stage or will be just one component in a series that requires moving on to the next process, which is welding.

Welding is a skilled practice and the artistry of the welder is to take the component parts shaped and formed previously and weld all the pieces together to make the final product in accordance with the design. This final assembly is critical and it is up to the welder to use the welding technique necessary for the job in hand.

Metal fabrication is essential to heavy industry such as mining. The manufacturing of support equipment, skids, conveyor belts, tanks, crushers, drill rigs and hydraulic lifting equipment through to pipe work are all the result of the metal fabrication process. In the mining industry there are very often special requests for one off pieces of equipment that are needed in a hurry and the metal fabrication business that can design and manufacture the product to implementation on site is the company that has the advantage. Metal fabricators may also be called upon to repair equipment or weld a broken object. Mining relies upon rugged, tough machinery often needing custom manufacturing or enhancements making metal fabricators an essential support service to the industry.

Reputable metal fabricators have the ability to design high quality, complex products with precision and manufacture them to full compliance with the specification, which is essential to mining companies who need to be operational at all times. Other metal fabrications for the mining industry include chutes, bins, screen stands, safety guards, stairs, catwalks, platforms and wear plates.

Metal is an essential material for mankind and industry and has the ability to be recycled over and over again which makes it a valuable resource for the global environment. The long working life of all metal fabrications due to its durability means once your product is manufactured, you will not have to worry about it, as it is highly unlikely it will need your attention again.

The mining industry is reliant upon the equipment and the expertise of metal fabricators not only for mine construction but also for ongoing support and maintenance in such rugged environments. For metal fabrication Mackay or metal repairs Mackay, contact 3D Engineering Mackay today.

The Wonders of Polystyrene

Polystyrene is one of the most popular plastics produced today. It is used in a variety of industries, for the production of materials as diverse as packaging for shipping to thermal insulation for homes. There are several types of polystyrene, each offering unique properties influenced by the process used to produce the plastic.

Extruded polystyrene foam (sometimes referred to by the Dow Chemical brand name, Styrofoam) is an amazing material for construction work or any insulation needs. The extrusion manufacturing process produces a “closed cell” type of plastic, a material with an exceptional degree of mechanical strength which also offers excellent water resistance and low thermal conductivity. Low thermal conductivity makes extruded polystyrene an ideal material for insulation in buildings and other applications. The closed cell structure offers high water resistance allows for usage even in wet or humid environments like might be encountered on roofs, walls or even in refrigerated environments where condensation is a leading concern.

Extruded polystyrene is lightweight, nontoxic and easy to work with. It can be cut and bonded with no hassle, giving construction workers the ease of use that lets them get the job done quickly and efficiently. Even very large sections are lightweight and easy to handle, while still managing to provide amazing mechanical strength, high compression strength and impressive thermal insulation properties. Polystyrene insulation is a favored building material, widely used worldwide in private and commercial applications.

Today polystyrene insulation can be found in almost any building. It is used as the structural core and insulation in walls, floors, roofs, refrigerated trucks, cold rooms, and a multitude of other applications. Its useful water resistant properties have even seen polystyrene used as an effective flotation device in the early days of its development, but its most successful applications have been found in building insulation. Buildings insulated with polystyrene can be much more effectively heated or cooled. The low thermal conductivity makes sure your building retains the heat when its cold but can also breath and release heat when its hot.

Architects and contractors have found ways to make polystyrene work for them outside the construction site. It is often used as a material for architectural models. Similarly, it has found applications in the hobbyist recreational model market. While marketed primarily as a building material, the range of possibilities for extruded polystyrene is only limited by your creativity. It has been used by great effective in unorthodox and exciting new ways by tinkerers and inventors the world over.

The production of extruded polystyrene materials is a careful process that has a history spanning back nearly two hundred years. It is a tale of mind boggling advances in chemistry, engineering and modern manufacturing. Today, modern polystyrene products are the result of decades of work by some of the most brilliant minds of the last two centuries. The combination of all this genius has produced an ideal high quality plastic material which provides enough mechanical strength and proper thermal conductivity properties to serve as one of the essential pieces of the modern contractors toolkit. Polystyrene is an invaluable tool which the world would look quite different without.

Laser Clinic Brisbane

IPL (Intense Pulsed Light) is a light based technology which treats several skin conditions in one treatment. It works in the deeper layers of the skin where traditional skincare cannot reach, thus achieving a far superior result.
Skin concerns such as pigmentation, freckling, sun damage, capillaries, redness, acne scarring and rosacea may be treated with photorejuvenation.

Pulses of light are applied to the skin via a handpiece which filters the wavelengths of light through a layer of ultrasound gel. The treatments remove most types of sun induced pigmentation like freckling, age spots and sun damage. By lessening the darker pigmentation IPL leaves the skin with a more even tone. Vascular skin concerns including capillaries, redness, acne scarring and rosacea are also targeted by the broad wavelengths of light. IPL works particularly well on red acne scarring that is left behind after undergoing acne treatments.

As most people will have several skin concerns, this treatment has become popular as it can address them all. The IPL photorejuvenation also stimulates the production of collagen which will plump and smooth the texture of the skin, improving fine lines, wrinkles and pitted scarring.

There is little or no downtime involved with photorejuvenation. Most people will experience some redness and heat in the area which subsides in several hours after treatment. The most common treatment areas are face, neck, décolletage/chest area and backs of hands.

Photorejuvenation treatments can be utilised as a once off treatment, however a course of treatments will promote the best results. A progressive result can be expected with a change usually noticed within a week after a session which is why IPL Photorejuvenation has gained such popularity among both men and women.

Things to know before you buy night lights

Night Lights are small light resources that are kept on during the night. The intention behind using night lights is to help people find their way in the dark or to help individuals who are afraid of the dark. While choosing the best night lights for you, it is necessary to consider two things: how bright you want these lights to be and howimportant is energy efficiency to you.

What type of night lights are available on the market?

Incandescent Night Lights
The most common night lights use the traditional incandescent bulb. This type of bulb uses a wire filament for the production of light and is not much energy efficient. Most of the incandescent night lights come in the 5-10 watt range.

Fluorescent lights
A fluorescent night light uses almost the same amount of energy to provide a better light output. These lights use about 7 watts of power.

Neon lights
Neon Light offers an energy-efficient alternative by using just about 1 watts of energy. Neon lights carry a small amount of neon gas, which lights up when electricity goes through it. These lights are just outlet-mounted strips that have an electro-luminescent surface. Just like glow-in-the-dark paint or stickers, these night lights emit light while using a negligible amount of power, which is less than even .07 watts.

Things to consider before you buy night lights

The way these lights are powered
Most important thing to consider when buying a night light is how they are powered. Most of the lights are made to be plugged into a wall outlet. However, it is also possible to buy a design that is powered by a battery.

The type of bulb used
One important thing to consider when buying a night light is the kind of bulb used. Night lights that use incandescent bulbs are less energy efficient compared to other designs. Though night lights that use luminescent bulbs are less energy efficient, they produce a much brighter light. They’ll also last considerably longer than their incandescent counterparts will.

Features to look out for

Sensor
Some lights have photosensitive triggers in them that automatically turn off the light when there is an ambient light source present and when bigger overhead lights are on. This sensor also detects the darkness and turns on the light automatically. There are also lights available with sound sensors.

Power modes
Some manufacturers of lights and bulbs also make bulbs with two different modes. In their power mode, they act as a standard 60-watt bulb that gives off enough light to light up the room. In their second energy-saving mode, which may be reached by flipping the switch twice or after twenty minutes of waiting, the bulb automatically dims itself to a 7- W bulb, which is perfect for a night light.

Programmable
Buying a programmable night light will allow you to fix the number of hours for which the light will be operational. This makes these lights much more energy efficient.

Music
Some night lights also play music to assist you in falling asleep. There’re also designs available that have the ability to play specific music. With these kinds of night lights, it is best to select a model that comes with a timer so that it turns off automatically after ten or fifteen minutes.

These were just a few tips to help you make the right decision when you are out to buy night lights. If you want your night lights to be energy efficient, look for ones that use neon bulbs.
