Butler Blown Film Technology, LLC Lake Jackson, TX 77566can be drawn down to thin gauges while maintaining superior mechanical properties making these polymers well suited for blown film extrusion. However, because LLDPE polymers have relative low melt strength ;Cast film is usually made in a thickness range of 20 to 200 microns, and is used in applications that require superior optical properties such as gloss, transparency, surface smoothness, planarity and good tear resistance.;quantity of LLDPE produce worldwide for the film blowing market, it is of interest to investigate the roles of slip agent in blown film process. The objective of this work is to assess the effect of different contents of slip agent (0, 800, 1,000, 1,200 and 1,500 ppm) on the surface friction and tensile properties of LLDPE films. 2. EXPERIMENTAL;Blown stretch film is manufactured using the blown film extrusion process. Typical characteristics are: poor optics, hazy, dull, excellent puncture resistance, noisier unwind, and high force on load. PE ;Tekpak’s Blown Stretch Film is advantageous when conquering loads that contain pointy edges. With its blown process, the film can unitize heavier goods on pallets. It provides a high degree of memory when stretched, which secured the loads. Common Sizes: 500 mm x 400 m x 25 mic 18” x 1500’ x 90G Available in:;As a professional Polyethylene PE Film China manufacturer, we are holding several multi-layer co-extrusion lines with a monthly capacity of 3,000 metric tonnes, serving thickness from 0.01mm (10micron) to 0.18mm (180micron), for the applications of wrapping, lamination, composite, printing, stretch, heat shrink, protection, and so on.
Stretch Wrap 101 Everything About Stretch Wrap!
Blown stretch film is a premium quality film. Blown stretch film has a higher degree of memory once stretched, allowing product loads to stay better secured. Higher tear resistance is an advantage when securing loads with sharp edges. Disadvantages of Blown Stretch Wrap- Higher cost due to the manufacturing process.;Blown stretch film tends to: be very resistant to puncture; have higher levels of “cling” (how the film ‘sticks’ to itself) make more noise unwinding; Cast stretch films often: are clearer shinier on a load; unwind quieter; resist tear ;Plascon produces blown film in a state of the art manufacturing facility located in Traverse City, Michigan. We can produce Flat, Star Seal or Gusseted Tubing or produce individually cut bags. Films can be from 6″ to 55″ wide (depending on seal ;Our machine grade film line consists of one-sided, two-sided, differential cling and ultraviolet inhibiting cast and blown films. Blown Films: Blown stretch film provides greater tear resistance, tension retention and scuff ;The memory of blown stretch film is superior to cast stretch film. This means that once stretched, blown stretch film stays tighter to the load over a longer period of time. Blown stretch film also has superior tear resistance and is great for wrapping loads with sharp edges. Disadvantages- Cost is the primary disadvantage of blown stretch film.;Blown film generally has a better balance of mechanical properties than cast or extruded films because it is drawn in both the transverse and machine directions. Mechanical properties of the thin film include tensile and flexural strength, and
Cast Stretch Films BP Plastics
Stretch film is a highly stretchable plastic film that is used for wrapping around products and keeping wrapped-items tightly bound. It is widely used in pallet wrapping to keep palletised goods sturdy thus improve warehousing and logistics efficiency and safety, while also being used in bundling smaller items.;Huahang Excellent Tear Resistance Good Self-Adhesiveness 3-Layer Blown Stretch PE Film, Machine Hand Use Stretch jumbo Roll. $6.30-$6.90 / Roll. 300 Rolls (Min.

With excellent films, we will also work with you ;Blown films, also commonly known as tubular films, are created by extruding plastic through a tubular-shaped die and then stretched and blown with air to create a very thin-walled film. Polyethylenes such as LDPE, LLDPE and HDPE polymers are common resins that are used to create blown films.;Blown films are pre-stretched by virtue of their manufacturing process. Bi-Orientated Extrusion (Tenter Frame) is different, made by extruding melted resin horizontally through a flat die then
