Profile sealing flange

A profile sealing strip for affixing to a package and thereby providing said package with a resealable closure, comprising:

• a sealant layer having a first and second portion, each of said portions having a length, a closure profile side, and a plurality of ribs extending along said length from said closure profile side, adjacent ones of said plurality of ribs forming a channel therebetween;
• a lateral flange having first and second sections, said first and second sections each having an outer surface and an inner surface, said outer surface of said first section of said lateral flange being connected to an end segment of said plurality of ribs on said first portion of said sealant layer, said outer surface of said second section of said lateral flange being connected to an end segment of said plurality of ribs on said second portion of said sealant layer;
• and
• a closure portion having a closure means and a base, said base having a bottom and being disposed between and connected to said first and second sections of said lateral flange, said closure means protruding beyond said inner surfaces of said first and second sections of said lateral flange.

A profile sealing strip affixed to a package to provide said package with a resealable closure, comprising:

• a lateral flange having first and second sections, said first and second sections having a length, an outer surface, an inner surface, and a plurality of ribs extending along said length of said outer surface, adjacent ones of said plurality of ribs forming a channel therebetween adjacent said outer surface;
• a closure portion having a closure means and a base, said base being disposed between and connected to said first and second sections of said lateral flange, said closure means protruding beyond said inner surfaces of said first and second sections of said lateral flange;
• and
• a sealant layer having a first portion and a second portion, said first portion of said sealant layer being affixed on surfaces of said plurality of ribs located on said first section of said lateral flange and to a surface on said package, said second portion of said sealant layer being affixed on surfaces of said plurality of ribs located on said second section of said lateral flange and to a surface on said package.

A method of attaching a profile sealing strip to a package, said profile sealing strip including a lateral flange with first and second sections, a closure portion, and a sealant layer;

• said first and second sections of said lateral flange each having a length, an outer surface, an inner surface, and a plurality of ribs extending along said length of said outer surface, adjacent ones of said plurality of ribs forming a channel therebetween;
• said closure portion having a closure means and a base, said base being disposed between and connected to said first and second sections of said lateral flange, said closure means protruding beyond said inner surfaces of said first and second sections;
• and
• said sealant layer having a first portion and a second portion, said first portion of said sealant layer being affixed to an outer segment of said plurality of ribs on said first section of said lateral flange, said second portion of said sealant layer being affixed to an outer segment of said plurality of ribs on said second section of said lateral flange;
• said method comprising the steps of:
• positioning said profile sealing strip adjacent said package with said sealant layer contacting said package;
• placing a heat-sealing bar against said package;
• applying heat to said package by said heat-sealing bar, said heat conducting through said package and into said sealant layer, said heat being substantial enough to raise the temperature in said sealant layer above a melting point of a material comprising said sealant layer, said material flowing into said channels between said ribs;
• applying pressure to said sealant layer;
• cooling said sealant layer to a temperature below said melting point of said material comprising said sealant layer;
• and
• relieving said pressure from said sealant layer.
