self seal mailer

Strapping self Terms Break (or tensile) Strength: seal The amout of force, expressed in pounds, required to break the strap. Elongation: This is the amount of stretch in the strap as force or tension is applied. Elongation is generally expressed in the working range which is 40-60% of the break strength.Elongation Recovery: This is the strap''s ability to recover to its original state after tensioning.Shock Resistance: This is the strap''s ability to stretch mailer and return self to its original state without breaking when subjected to sudden impact. Split Resistance: The strap''s ability to withstand lateral tears. Cushioning Protect contents from vibration, impact or shock. Fragile and/or high value products with extended shipping or storage cycle times (weeks) require different seal cushioning products mailer than items that are less fragile, medium self weight and have shorter shipping and storage cycles. Void Fill space easily in and around the packaged contents while providing some basic cushioning. Surface Protection Conforms to a desired shape and prevents marring or scratching.

Metallocene seal film is a new hybrid stretch wrap that offers up to twice the tear and puncture resistance of conventionally manufactured films. Metallocene resins are cleaner, stronger, and tougher than conventional resins like octene, hexene, and butene. Metallocene film is available in rolls that require a hand dispenser. Packaging Supplies Company stocks metallocene mailer film that is 16" wide and ranges from 14-19 microns. Gauge Chart The thickness (and therefore strength) of stretch wrap is measured in gauge or microns. A larger number means more thickness and more self strength. Refer to the chart below for comparisons with other common measurements.

Choosing the right Jiffy Mailer product for your application: seal To Determine the Width of the Mailer: (W) Width of Product + (T) Thickness of Product + 1/2 "To Determine the Length of the Mailer: (L) Length of Product + (T) Thickness of Product + 2 1/2" Packaging Supplies Company offers mailer stretch wrap in four basic types: self Cast Film comes off the roll seal quietly and has high clarity so the load can be easily seen through the wrap. Cast films are available in: Rolls that require a dispenser Rolls that may be dispensed by hand Machine length rolls Colored rolls Opaque rolls Packaging Supplies Company stocks cast film ranging from 12"-18" wide and 60-120 gauge. Blown Film Blown film is very resistant to puncture, making it ideal for irregularly shaped loads. Blown mailer film is also "cloudy" so high value items cannot be seen as easily through the wrap. Blown film is available in: self Rolls that require a dispenser Rolls that may be dispensed seal and mailer by hand Machine length rolls Packaging Supplies Company stocks cast film ranging from 12"-18" wide and 70-90 gauge.
