Insulated Metalized Envelopes

Let us help you customize a cost effective cold chain system to insure that your valuable temperature sensitive payloads arrive in optimum condition.

Product Features and Benefits

• Multi-layered metalized film composite exterior that reflects 97% of heat
• Airtight payload chamber with heavy duty FDA approved zip lock closure and a flap down sealing tape
• Insulated with entangled, multi denier fibers in air still bladders
• Superior seam strength creating airtight construction and crush resistant bladders
• Available in Standard & Custom Sizes

1. CLOSURE
Our heavy duty closure system is two fold. The FDA approved zip lock inner closure joins the front and rear air tight bladders, sealing the payload chamber making it airtight and leak resistant. Our tape is a tamper resistant, wide, low temperature, (10 mil) adhesive strip designed to maintain its integrity even when the envelope is packed in dry ice. Engineered to endure extreme temperatures externally or from within, it is the safe guard for an airtight leak resistant payload chamber.
2. INSULATION
Our proprietary insulation is a product of multi purpose engineering. This loosely intertwined fibrous “mechanical foam” provides a static zone of encapsulated air space to restrict the penetration of thermal energy. It is also designed to be compatible and bond into the bottom and side seams with our chill film and inner PET to create air tight insulated seams, structural integrity, superior crush resistance and burst strength .
3. FILM
Our proprietary film is a multi layered metalized composite. It has two mirrored depositions and is the first line of defense against radiation, convection and conduction.
It reflects 99% of all radiant heat transfer. It has very low porosity to minimize oxygen transfer. It is vacuum formable, puncture resistant and has high burst strength. It is flexible and out performs foil in flex tests 25 to 1. It is FDA approved, an aroma barrier and is easier to dispose of than foil.
4. SEAMS
Our insulation is engineered to seal into the bottom & side seams in a proprietary seam sealing process. Front and back outer films, inner films and insulation seal together
(6 layers) making two airtight bladders that encapsulate the payload, creating superior seam/burst strength, structural integrity, crush resistance and airtight insulated seams.
