Packaging material 10 for a sealable, easy opening, tear resistant pouch-like package 100 comprises a first layer 12 including an oriented polymeric material having a front side capable of receiving surface printed information. A second layer 16 bonded to the first layer 12 includes a light barrier and moisture impervious material. Bonded to the second layer is a third layer 18 comprising a a coextruded film comprising carbon black-loaded linear low density polyethylene-EVA-polybutylene or carbon black loaded linear low density polyethylene film with an EVA gel lacquer coating. The material 10 overwraps the photographic product in a pouch-like structure comprising a flap 120, having along its length, a lengthwise seal 123 projecting outwardly of a second side 114. Second side 114 along with a first side 116 of package 100, extend between opposed hermetically sealed rearward and forward end portions 116,118.

Peelable pouch-like packaging for photographic sheet film

An improved light-tight package for a roll (10) of a length (14) light-sensitive material such as photographic film or paper includes an opaque leader (22) provided with adhesive elements (44, 46) which adhere more strongly to the leader that to folded-over portions (58, 60) of opaque end disks (32, 34). Alternatively, adhesive elements (56) having similar properties may be applied to the end disks. Upon unrolling of the package by pulling the leader, the end disks release from the adhesive elements without tearing; and the adhesive elements remain attached to the leader and are removed from the roll with the leader.

Light-tight package

A package system 10 for storing and transporting photographic film products in an environment substantially free of dirt, light and moisture has a support member 12 comprising a first portion 14, a medial portion and a second portion 16. The first and second portions 14,16 each comprise a plurality of spaced openings 24 for receiving a partial portion of the product in a substantially locked relation with the first and second portions 14,16, respectively to restrict translational movement of the product in the support member 12. A pair of spaced single foldable scored lines 17,19 in the medial portion of the support member 12 forms an end wall 20 therebetween that spatially separates the first portion 14 from the second portion 16. When product are nested in the first portion 14 of the support member 12 and the second portion 16 is brought into folded engagement with the an opposite portion of the nesting product, a container 30 is formed. The container 30 is then overwrapped and hermetically sealed with a flexible light shielding and moisture impervious barrier material to form the package 10.

Flexible photographic film package

A package structure 10 for storing and transporting photographic film magazines comprises a container 12 having a open end 24 and a base 14 supporting opposing end walls 16 and opposing side walls 20,24. Side walls 20,22 have a plurality of spaced apart recesses 32,34, respectively, forming chambers or receptacles 30, for frictionally receiving the end portion and the hub extending from the opposite end portion of the 135 photographic film magazines disposed therein. A lid member 26, made from a flexible opaque laminate material environmentally compatible with the container 12, is hermetically sealed to a flange member 42 formed in the top edge 28 of the end and side walls 16,20,22. The sealed package 10 protects the enclosed product from deleterious environmental effects, such as dirt, light and moisture, and is convenient to use.
