Microwave popcorn package heat seal jaw
The patent application (Publication Number: US20230405960A1) describes a heat seal jaw designed for forming a heat seal in a microwave popcorn package. The heat seal jaw includes a heat seal body portion with tapered seal portions on both sides to prevent non-seal edge portions from coming into contact with the paper and adhesive of the package, thereby avoiding moisture flashing that could lead to bubbles or voids in the adhesive. The taper angles range from about 50 to 70 degrees, ensuring effective sealing without compromising the integrity of the package.
Furthermore, the patent application details a process for forming a microwave popcorn package using non-fluorocarbon materials. The process involves laminating two paper plies coated with a flexible adhesive and forming a longitudinal seal using the described heat seal jaw. The seal portion of the heat seal jaw is designed with specific taper angles and cross-sectional widths to optimize the sealing process and prevent moisture-related issues. By utilizing this innovative heat seal jaw and process, the resulting microwave popcorn package can maintain structural integrity and prevent potential defects caused by moisture exposure during the sealing process.
