Abstract

Provided is a perforated plastic bag wherein the volume of said bag is 100 liters or more; wherein the average perforation diameter is 500 micrometers or less; wherein said plastic bag comprises a lower zone and a top zone, wherein the perforation density of said lower zone is greater than the perforation density of said top zone. Also provided is a method of using such a plastic bag.

First claim

What is claimed is:

1. A package comprising
a box and
a non-uniformly perforated plastic bag located within the box,
wherein the non-uniformly perforated plastic bag comprises a lower zone having a perforation density and a top zone having a perforation density, and
wherein the perforation density of the lower zone is greater than the perforation density of the top zone.

2. The package of claim 1 , wherein the box comprises holes having a diameter of about 20 mm or higher.

3. The package of claim 1 , wherein a ratio of the perforation density of said lower zone to the perforation density of said top zone is 1.1:1 or higher.

4. The package of claim 1 , wherein the package does not include kraft paper liner.

5. The package of claim 1 , wherein the package further comprises a kraft paper liner located between a portion of the non-uniformly perforated plastic bag and a bottom of the box.

6. The package of claim 5 , wherein a portion of the kraft paper liner is located between the lower zone of the non-uniformly perforated plastic bag and the top zone of the non-uniformly perforated plastic bag.

7. The package of claim 5 , wherein the box comprises a first side, a second side, and the bottom of the box extends between and interconnects the first side and the second side.

8. The package of claim 7 , wherein the kraft paper liner has a first end and a second end and the kraft paper liner is arranged so that a portion of the first end is located between the second end and the bottom of the box.

9. The package of claim 8 , wherein a portion of the top zone of the non-uniformly perforated plastic bag is located between the first end of the kraft paper liner and the side of the box.

10. The package of claim 5 , wherein the kraft paper liner comprises perforations having a diameter of about 0.5 cm or higher.

11. The package of claim 1 , wherein the non-uniformly perforated plastic bag is closed by a gripping device.

12. The package of claim 11 , wherein the gripping device is a rubber band or tape.

13. A non-uniformly perforated plastic bag comprising
i) a top zone having a banana-specific perforation defined as a total area of perforations in the top zone divided by a mass of bananas enclosed by the top zone, and
ii) a lower zone having a banana-specific perforation of about 0.025 mm 2 /kg or more, defined as a total area of perforations in the lower zone divided by a mass of bananas enclosed by the lower zone,
wherein a ratio of the banana-specific perforation of the lower zone to the banana-specific perforation of the top zone is about 6:1 or less.

14. The non-uniformly perforated plastic bag of claim 13 , wherein the banana-specific perforation the top zone is about 3 mm 2 /kg or less.

15. The non-uniformly perforated plastic bag of claim 13 , wherein the banana-specific perforation of the top zone is about 0.05 mm 2 /kg to about 2 mm 2 /kg.

16. The non-uniformly perforated plastic bag of claim 13 , wherein the ratio of the banana-specific perforation of the lower zone to the banana-specific perforation of the top zone is about 0.3:1 or higher.

17. The non-uniformly perforated plastic bag of claim 13 , wherein the ratio of the banana-specific perforation of the lower zone to the banana-specific perforation of the top zone is about 0.4:1 to about 5:1.

18. The non-uniformly perforated plastic bag of claim 13 , wherein the non-uniformly perforated plastic bag includes a first set of lines of perforation and a second set of lines of perforation that are generally shorter than the first set of lines of perforation.

19. A package comprising
a box, and
a non-uniformly perforated plastic bag located within the box,
wherein the package is configured with the means for maintaining atmospheric conditions inside the non-uniformly perforated plastic bag so that harvested bananas can be stored in the package for 7 to 20 days.

20. The package of claim 19 , wherein the non-uniformly perforated plastic bag comprises a lower zone and a top zone, each of the lower zone and the top zone having a perforation density, and the perforation density of the lower zone is greater than the perforation density of the top zone.
