A reclosable, hermetically-sealed flexible package which has an inner, hermetic pool seal and a reclosure seal comprised of interlocking closure strips is provided with a tamper-evident feature located peripheral to the reclosure seal. The tamper-evident feature must be visibly disrupted to gain access to the reclosure seal.

Tamper-evident, reclosable, flexible packages

A food package comprising a rigid plastic base tray having at least three compartments, the tray being covered by a flexible film which is airtightly sealed to flanges of the tray to airtightly or hermetically seal the respective compartments. A label structure integrally associated with the flexible film has opaque areas for label information and transparent areas for viewing the product. The label structure may be formed by separate pressure sensitive labels, by printing on the flexible film itself or by a shrink wrapped band with printing thereon. A structure associated with the bottom of the tray may provide rigidity, protect the bottom of the tray, provide an additional area for commercial information and/or provide a stand-up feature. The materials of the package may be selected to maximize recyclability.

Food package having a compartmentalized rigid base tray

A multi-seal flexible recloseable package having a tapered product cavity formed in one of the package sidewalls has a generally wedged-shaped cavity into which a doubled-over shingled stack of the food product slices are sealed. The package has a first, peelable hermetic seal located next to an access edge of the product cavity and a second, recloseable seal positioned directly above the peelable seal. Vertical extensions of the package sidewalls are sealed together at their tops to form a third package seal which has a tamper-evident tear strip. One or more openings in the vertical package extensions allow the package to be supported on a display hook.

Multi-seal recloseable flexible package for displaying thinly sliced

A recloseable package has discrete, multiple product portion enclosures between first and second package films. Each product portion enclosure is separated from its adjacent product portion enclosure by a package central web portion. A recloseable seal is provided on the central web portion for each multiple product portion enclosure, and the product is hermetically sealed in its portion enclosure by a hermetic seal extending around the periphery thereof and interior of each recloseable seal.

Multiple portion recloseable package

A reclosable, hermetically-sealed flexible package which has an inner, hermetic peelable seal and a reclosure seal, typically including interlocking closure strips, is provided with one or more of various tamper-evident features which provide an easily visible and noticeable indication of disruption thereof of the type that would gain access to the reclosure seal.

Tamper-evident, flexible, reclosable package

A hermetically sealed food product package is provided having a vacuum sealed or gas flushed and sealed product cavity and having a preformed perforated or cutaway portion on at least one of the sheets of film forming the package to allow easy separation of the package in order to gain access to the vacuum or gas flushed product cavity.

Easy separating package and method

Multi-seal reclosable flexible package for displaying thinly sliced food

A food package container including a base and a body in alignment with and peelably sealed to each other is provided. At least one of snap closure assembly is provided on the respective peripheral flanges of the base and body, and this snap closure assembly provides an audible snapping signal when the consumer recloses the food packaging container. The closure assembly includes an insertion projection and an opening in general registry therewith which is undersized with respect to the projection.

Reclosable food packaging having snap closure and method of making same

A reclosable, hermetically-sealed flexible package which has an inner, hermetic peel seal and a reclosure seal comprised of interlocking closure strips is provided with a tamper-evident feature located peripheral to the reclosure seal. The tamper-evident feature must be visibly disrupted to gain access to the reclosure seal.

Tamper-evident, reclosable flexible packages

This invention pretains to a reclosable package having a body member, a base, a hermetic seal between the body member and base and snap locking projections in the side walls of the body member and base.

Food package containing a reclosable means

A food package having a rigid base tray formed of resilient material and having a plurality of recessed compartments, at least some of said recessed compartments containing food products and being air-tightly sealed with a flexible film. The rigid base tray is enclosed within a sleeve which includes front and back panels connected together by upper side and lower side panels. The sleeve may include a feature permitting the package to be displayed upright. The sleeve would include a structure for easily breaking the sleeve so that the consumer can easily reach the contents of the rigid base tray.

Food package having a sleeve enclosure and a rigid base tray

A reclosable package comprising interlocking closure strips positioned outside of a hermetic seal or seal area and the method for producing and filling same. The hermetic seal is of the easy-open or peelaway type so as to not destroy the integrity of the package or closure strips upon opening of the package.

Method of making a reclosable package

A package is provided which incorporates a peel seal area or areas that provide readily detectable evidence that the package has been opened or tampered with. Message indicia are provided at the peel seal, and the appearance of the message indicia changes when the peel seal area, which has a contact clarity condition when sealed, is broken resulting in the onset of an opacity condition which thereby obscures message indicia and/or makes message indicia visible in order to inform a consumer or potential purchaser that the peel seal has been broken.
