Abstract

A quad-seal package has a front panel, back panel, first side panel, and second side panel formed from a recyclable packaging film. The recyclable packaging film includes a machine-direction oriented, polyethylene-rich exterior film and a polyethylene-based interior film. The quad-seal package, when containing a granular product, resists rupture when dropped according to ASTM D5276-98 test procedure A2.2.1 on the bottom of the package at a drop height of 91.4 cm (36 inches).

First claim

What is claimed is:

1 . A packaged product comprising:
a granular product; and a bag comprising a front panel, a back panel, a first side panel, a second side panel, a top seal, a first side seal, a second side seal and a bottom seal; wherein the first side seal comprises a front leg portion bonding the front panel to the first side panel, and a back leg portion bonding the back panel to the first side panel; wherein the second side seal comprises a front leg portion bonding the front panel to the second side panel, and a back leg portion bonding the back panel to the second side panel; wherein each of the front panel, the back panel, the first side panel, and the second side panel comprises a recyclable packaging film comprising a polyethylene-rich, oriented exterior film, a polyethylene-based interior film and an adhesive layer connecting the exterior film to the interior film; wherein the interior film comprises a sealing surface comprising a first outer layer of the interior film that can be exposed to the granular product; wherein the interior film comprises a laminating surface comprising a second outer layer of the interior film that is exposed to the adhesive layer; wherein the bag contains the granular product; wherein the bag comprises a top and a bottom; and wherein the packaged product resists rupture when dropped according to ASTM D5276-98 test procedure A2.2.1 on the bottom of the bag at a drop height of 91.44 cm (36 inches).

2 . The packaged product according to claim 1 , wherein the laminating surface of the interior film comprises a polyethylene comprising a melting temperature greater than 115.5° C. (240° F.).

3 . The packaged product according to claim 1 , wherein the first side seal further comprises a top portion bonding the front panel to the back panel and the second side seal further comprises a top portion bonding the front panel to the back panel.

4 . The packaged product according to claim 1 , wherein the bag further comprises a bottom panel constructed of a recyclable packaging film, wherein the bottom seal comprises a front portion bonding the front panel to the bottom panel, a back portion bonding the back panel to the bottom panel, a first side portion bonding the first side panel to the bottom panel, and a second side portion bonding the second side panel to the bottom panel.

5 . The packaged product according to claim 1 , wherein the bottom seal bonds the front panel to the back panel.

6 . The packaged product according to claim 1 , wherein at least one of the front panel, the back panel, the first side panel and the second side panel comprises a ventilation feature.

7 . The packaged product according to claim 1 , further comprising a zipper closure.

8 . The packaged product according to claim 1 , wherein the granular product comprises a weight from 1.36 kg to 22.68 kg (3 pounds to 50 pounds).

9 . The packaged product according to claim 1 , wherein the bag comprises an interior film thickness from 104 microns to 145 microns (4.1 mil to 5.7 mil).

10 . The packaged product according to claim 1 , wherein the exterior film is machine-direction oriented and comprises at least 95% polyethylene-based materials.

11 . The packaged product according to claim 1 , wherein the exterior film is machine-direction oriented and consists of one or more polyethylene-based polymers.

12 . The packaged product according to claim 1 , wherein the sealing surface of the interior film comprises a polyethylene comprising a melting temperature that is at least −6.67° C. (20° F.) lower than the laminating surface melting temperature.

13 . The packaged product according to claim 1 , wherein the adhesive layer is a two-component laminating adhesive.

14 . The packaged product according to claim 1 , wherein the bag comprises a total composition comprising between 90% and 99% polyethylene-based polymer, by weight.

15 . The packaged product according to claim 1 , wherein the bag comprises a total composition comprising at least 95% polyethylene-based polymer, by weight.

16 . The packaged product according to claim 1 , wherein the recyclable packaging film comprises a machine direction tear value and a cross direction tear value, each comprising greater than 17,000 mN (26.3 pound-force) according to ASTM D1922-09 as described herein.

17 . The packaged product according to claim 1 , wherein the recyclable packaging film comprises a print layer positioned between the exterior film and the interior film.

18 . The packaged product according to claim 1 , wherein the recyclable packaging film comprises a matte varnish on an exterior surface of the exterior film.

19 . The packaged product according to claim 1 , wherein the recyclable packaging film comprises a seal window comprising from 116° C. to about 149° C.
