The very nature of blown film makes it a pre-stretched product, and the thickness of blown film is adjustable dependent on the diameter of the tube from which it comes.

Cast Film. Cast film is created by feeding a sheet of heated resin through a flat die. The molten material emerges from the die and out onto larger chilling rollers which cool and solidify the material. It is then ready for trimming and rolling.The plastic carry bag is an established part of Australian shopping. The nation consumes approximately 6.9 billion plastic bags, or 36,850 tonnes of plastic, each year - this equates to just under one bag per person per day. About 53% of plastic bags are distributed from supermarkets, while 47% come from other retail outlets such as fast food shops, liquor stores, and general merchandising. One of the main methods of managing the use and disposal of plastic bags is the voluntary National Code of Practice for the Management of Plastic Retail Carry Bags (Australian Retailers Association 2002).

Plastic bags are popular with consumers and retailers because they are a functional, lightweight, strong, cheap, and hygienic way of transporting food and goods. Additionally, the manufacture of plastic bags uses little energy. However, research has shown that energy use and greenhouse gas emissions can be reduced by switching from the commonly used bags to larger, reusable bags, by expanding the Code, and introducing a levy. These options are discussed briefly below.One of the most frequent questions we get asked by our clients is: what is the main difference between a woven bag vs. a non-woven bag? Our blog explains technical and design features to help you design and manufacture unique branded products. Now that we have launched our new website for Patented Reflective Bags, it is important to understand not only the benefits of reflective piping but also the raw materials involved.

How a Printing Press Works

printing press is a complex piece of high-precision industrial equipment that is designed to produce printed material at a high rate of speed and low cost per page. Printing presses are commercially available which use several different types of printing technologies, but the most common type is called offset lithography. These presses are commonly designed in either sheet-fed configurations, which print on individual sheets of paper or other material, or web-fed configurations, which print on long webs of paper or other material, supplied on large reels. A so-called 'full size' sheet fed offset press prints on sheets that are about 700 mm x 1000 mm in size (about 28 inches x 40 inches). "Half size" and "quarter size" offset presses are also common, and these machines print on sheets which are one-half or one-quarter as large.

An offset printing press has a separate printing unit, or tower, for each color of ink. Some presses have as many as 12 towers, first printing 6 colors on one side of the sheet, then flipping the sThe most annoying aspect of recycling—and one of the biggest hurdles to its widespread adoption—is having to separate paper, glass, and plastic before they hit the curb. New recycling machines are changing that. With single-stream recycling, recyclables go into one bin, which a truck delivers to a materials-recovery facility, such as Willimantic Waste Paper in Willimantic, Connecticut. There, a largely automated system of conveyor belts, screens, magnets, and lasers separates materials so that they can be sold to metal and plastic recyclers and paper mills.
