Key Features

• EXCEPTIONAL QUALITY: Our bags are BPA Free and have rounded corners to protect your other stored items from puncture or damage. The strong Mylar film has a burst strength of 70 psi, equivalent to the weight of 2 1/2 cinder blocks per square inch. These bags are strong, durable, and easily seal with a vacuum-sealer, iron, or hair-straightening iron.

• LOW OXYGEN TRANSMISSION RATE: Mylar bag films provide three layers of protection and offer an extremely low Oxygen Transmission Rate (OTR) due to its thick foil laminate layer. This safeguards your food against the elements for long-term preservation.

• DURABLE LONG-TERM STORAGE: 5.5 Mil Heavy Duty Mylar bags provide a substantial increase in puncture protection, improved durability, and greatly increase long-term oxygen and moisture resistance. Superior oxygen barrier provides over 100 years of protection.
  
  
• RESEALABLE: This bag has a Seal-Top feature similar to sandwich bags. Seal-Top Mylar bags allow for opening/closing after tearing the heat seal portion to keep product fresh. For the longest term storage, heat seal above the zip seal.
