Abstract
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.
Claims17
A compostable sealing member for sealing to a rim surrounding a container opening, the compostable sealing member comprising:
- a multi-layer laminate including an upper laminate portion bonded to a lower laminate portion,
- the lower laminate portion positioned below the upper laminate portion and including at least one film layer and a sealant layer for bonding to the container rim, the upper laminate portion being bonded to the lower laminate portion through a partial layer of compostable adhesive to form a gripping tab for removing the sealing member from the container opening,
- the upper laminate portion including a support layer, and
- the compostable sealing member being substantially free of plastic materials.
A laminate for forming a compostable sealing member, the laminate comprising:
- an upper laminate portion including a support layer;
- and
- a lower laminate portion including at least one film layer and a sealant layer for bonding to the container rim,
- the upper laminate portion bonded to a lower laminate portion, the upper laminate portion being bonded to the lower laminate portion through a partial layer of compostable adhesive to form a gripping tab for removing the sealing member from the container opening, the laminate being substantially free of plastic materials.
A compostable sealing member for sealing to a rim surrounding a container opening, the compostable sealing member comprising:
- a multi-layer laminate including an upper laminate portion bonded to a lower laminate portion,
- the lower laminate portion positioned below the upper laminate portion and including at least one film layer and a sealant layer for bonding to the container rim,
- the sealant layer being a partial layer that is positioned above the rim when installed on the container opening,
- the upper laminate portion being bonded to the lower laminate portion through a partial layer of compostable adhesive to form a gripping tab for removing the sealing member from the container opening,
- the upper laminate portion including a support layer, and
- the compostable sealing member being substantially free of plastic materials.
A compostable sealing member for sealing to a rim surrounding a container opening, the compostable sealing member comprising:
- a multi-layer laminate including an upper laminate portion bonded to a lower laminate portion,
- the lower laminate portion positioned below the upper laminate portion and including at least one film layer, a sealant layer for bonding to the container rim,
- the upper laminate portion including a support layer,
- the upper laminate portion being bonded to the lower laminate portion through a partial layer of compostable adhesive to form a gripping tab for removing the sealing member from the container opening,
- a partial print layer that is positioned such that the compostable adhesive and partial print layer do not overlap, and
- the compostable sealing member being substantially free of plastic materials.
