5 Test Descriptions Test Preparation Two (2) thermocouples were placed inside each shipper (1 per wine bottle; 2 wine bottles per shipper); five thermocouples total. A hole was drilled into the cork of each wine bottle in order to place the thermocouple inside. While under test, the thermocouple sampled the temperature every 15 minutes during the conditioning profile. The fifth thermocouple was placed inside the chamber. Placement of the RTD sensors within the package systems is indicated below. Upright Bottles Shipper Report No A-R1 Page 5 of 19

During this time, the chamber and the temperature scanner were shut down. When the power resumed, the chamber continued with the conditioning profile. The temperature scanner was restarted and data collection resumed. The chart indicates only 24 hours dwell at +15 C but the boxes were conditioned for 25.5 hours. Westpak, Inc. is confident that the temperature remained steady during the power outage because the temperature did not change when the chamber resumed. Report No A-R1 Page 7 of 19

15 Conclusions and Recommendations Two (2) package systems containing 12-Pack Wine Bottles were subjected to temperature testing per ISTA 7D-2007, Cyclic Test Profile for winter and summer transport conditions for international shipments from the United States (72 hour International expedited airfreight transport). According to the winter and the summer thermal mapping data, there was little difference between the 12 bottle upright EPS wine shipper and the 12 bottom lay down wine shipper. The thermal properties of these two package types are similar as depicted in the graphs. Some slight resistance to heat transfer was noted at the center of the EPS package system, however, both packages attained equilibrium in less than a 12 hour period. The insulating characteristics of both package systems are considered to be equal regardless of location of the bottle within the package system. The test results and findings provided are only applicable to the unique materials tested. Because of the differing geometries, material thicknesses, and compositions of molded fiber wine shippers, and the cartons, it would not be appropriate to attribute the performance of the products tested to other products. Upon completion of this test procedure, the samples were returned to Western Pulp Products Company for final evaluation. The results of this evaluation are not known by Westpak, Inc. at this time. WESTPAK, INC. is pleased to present this report to Western Pulp Products Company covering the temperature testing of the 12-Pack Wine Bottles. The equipment used to conduct this testing has been recently calibrated and is known to be in good operating condition. In addition, the test operator uses good laboratory practice at all times. Therefore, the data is considered accurate and reliable. However, there is no warranty expressed or implied with the submission of this report, and Western Pulp Products Company assumes all liability for use of the data contained herein.
