摘要： Various enhancements of heat seals are provided herein with sealant layers that provide for decreased chance of oversealing the heat seal to a container. Such enhancements include the use of various types of resins in combination to provide for desirable heating and sealing characteristics. Further, the heat seals may be especially suitable for use with polyester containers, such as those containing polyethylene terephthalate.

摘要： Various forms of sealing members are described along with the laminates from which the sealing members are formed. In some forms, the sealing members may generally be formed from materials that may be compostable. In some forms, the sealing members are substantially free of plastic materials. In one form, the sealing members do not include any metal foil layers such as would traditionally be included in induction heated seals. Instead, the seals may be applied in other manners, such as using ultrasonic sealing, conduction heating, pressure sensitive adhesives, and the like.

摘要： Various forms of tabbed sealing members are described along with the laminates from which the sealing members are formed. In some forms, the tabbed sealing members may generally be formed from materials that may be processed using a single recycling stream. In one form, the tabbed seals do not include any metal foils, such as would traditionally be included in induction heated seals. Instead, the seals may be applied in other manners, such as using ultrasonic sealing, conduction heating, high frequency sealing/welding, pressure sensitive adhesives, and the like.
