Child Resistant Exit Bags, Pouches & Packaging

Materials Used To Make Child Resistant Mylar Stand Up Bags:

Below is a list of the different types and layers of films used to create child-resistant mylar bags. Choosing the correct materials ensures you get the needed barrier protection when packaging your product(s). 

 

• MBOPP:  Heat-sealable metalized biaxially oriented polypropylene film. The base material is BOPP with double heat-sealing layers, aluminum metalized on the treated side, and another heat-sealing layer on the other side.
• VMPET: Vacuum Metalized Polyester Film. Vacuum metalized film is usually designated to mean the polymer films with the surface deposited a thin layer of metal, usually aluminum, in flexible packaging applications through vacuum depositing
• LDPE: LDPE (low-density polyethylene) is a soft, flexible, lightweight plastic material. LDPE is noted for its low-temperature flexibility, toughness, and corrosion resistance. It is unsuited for applications requiring stiffness, high-temperature resistance, and structural strength.
• PET: Polyester (Polyethylene Terephthalate): Tough, temperature-resistant polymer. Biaxially oriented PET film is used in packaging laminates, providing strength, stiffness, and temperature resistance. It is usually combined with other films for heat seal ability and improved barrier properties.
• AL: Foil (AL or ALU): A thin gauge (6-12 microns) aluminum foil laminated to plastic films to provide maximum oxygen, aroma, and water vapor barrier properties. Although it is by far the best barrier material, it is increasingly being replaced by metalized films (see MET-PET, MET-OPP, and VMPET) because of cost.
• PE: Polyethylene: A simple thermoplastic polymer of ethylene. Highly puncture and tear-resistant. Not affected by extreme temperatures. Does not possess barrier properties. Good clarity.
