Accounting Policies [Abstract]
Summary of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The Company prospectively adopted the straight-line method of depreciation for manufacturing equipment, office equipment, and furniture and fixtures placed in service on or after February 1, 2015. This change was made as a straight-line method of depreciation more accurately reflects the economic consumption of these assets than did the accelerated method previously used. This prospective change in the depreciation method did not have a material effect on the Company’s financial position or results of operations for the three- or nine-month periods ended October 31, 2015. As described in Note 1 Summary of Significant Accounting Policies of the Company's Annual Report on Form 10-K for the fiscal year ended January 31, 2015, the Company assesses the recoverability of long-lived and intangible assets using fair value measurement techniques annually, or more frequently if events or changes in circumstances indicate that an asset might be impaired. An impairment loss is recognized when the carrying amount of an asset is below the estimated undiscounted cash flows used in determining the fair value of the assets. The cash flows used for this analysis are similar to those used in the goodwill impairment assessment discussed further below. As also described in Note 1 Summary of Significant Accounting Policies of the Company's Annual Report on Form 10-K for the fiscal year ended January 31, 2015, the Company recognizes goodwill as the excess cost of an acquired business over the net amount assigned to assets acquired and liabilities assumed. Management assesses goodwill for impairment annually during the fourth quarter and between annual tests whenever a triggering event indicates there may be an impairment. Impairment tests of goodwill are done at the reporting unit level. When performing goodwill impairment testing, the fair values of reporting units are determined based on valuation techniques using the best available information, primarily discounted cash flow projections. Such valuations are derived from valuation techniques in which one or more significant inputs are not observable (Level 3 fair value measures). In the fiscal 2016 second quarter the Company performed a Step 1 impairment analysis using fair value techniques on the Engineered Films reporting unit as a result of changes in market conditions indicating that goodwill might be impaired. The reporting unit's fair value was estimated based on discounted cash flows and that fair value amount was compared to the carrying value of the reporting unit. This analysis indicated that the estimated fair value of the Engineered Films reporting unit exceeded the net book value by approximately $50,700 or 37.2%. No significant changes were noted in the market conditions in fiscal 2016 third quarter and operating income was consistent with expectations at the end of second quarter. Although oil prices continue to be lower and sales are down, the profitability of the division continues to be higher than the trailing months at the time of the impairment analysis given the lower material costs in comparison to the selling price. As such, the Company concluded a triggering event did not occur in the current quarter for Engineered Films. In the fiscal 2016 third quarter the Company determined that a triggering event occurred for its Vista reporting unit, a subsidiary of the Aerostar Division. In addition to the Company making a change in the executive leadership of the Vista reporting unit during the quarter, financial expectations for sales and operating income of the reporting unit were lowered due to delays and uncertainties regarding the reporting unit’s pursuit of large international opportunities, one of which was expected to be awarded during the current quarter. While Vista has been in the process of negotiating a large international contract, the contract did not materialize in the fiscal 2016 third quarter as expected. The likelihood of being awarded this or other such contracts in the next twelve months is now lower than it was in the second quarter. The Company continues to pursue these international opportunities, but the timing of any contract award is less certain. As a result of a delay in being awarded this large international contract, the Company lowered its financial forecast for the business. As a result of these factors, the Company performed a Step 1 impairment analysis using fair value techniques as of October 31, 2015 for both long-lived assets and goodwill. As described in Note 7 Goodwill and Long-lived Asset Impairment Loss and Other Charges, the Company concluded that the Vista goodwill balance was fully impaired and that certain long-lived assets of the Vista reporting unit, including finite-lived intangible assets, were impaired as of October 31, 2015. Although the profitability of the Company’s other two reporting units, Aerostar (all operations other than Vista) and Applied Technology, has been down as compared to the prior year, the Company identified no triggering events requiring a Step 1 goodwill impairment analysis or long-lived asset impairment test for either of these reporting units. The Company will conduct its planned annual assessment of goodwill for impairment in the fourth quarter. There have been no material changes to the Company's significant accounting policies as described in the Company's Annual Report on Form 10-K for the fiscal year ended January 31, 2015.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The Company prospectively adopted the straight-line method of depreciation for manufacturing equipment, office equipment, and furniture and fixtures placed in service on or after February 1, 2015. This change was made as a straight-line method of depreciation more accurately reflects the economic consumption of these assets than did the accelerated method previously used. This prospective change in the depreciation method did not have a material effect on the Company’s financial position or results of operations for the three- or nine-month periods ended October 31, 2015.

As described in Note 1 Summary of Significant Accounting Policies of the Company's Annual Report on Form 10-K for the fiscal year ended January 31, 2015, the Company assesses the recoverability of long-lived and intangible assets using fair value measurement techniques annually, or more frequently if events or changes in circumstances indicate that an asset might be impaired. An impairment loss is recognized when the carrying amount of an asset is below the estimated undiscounted cash flows used in determining the fair value of the assets. The cash flows used for this analysis are similar to those used in the goodwill impairment assessment discussed further below.

As also described in Note 1 Summary of Significant Accounting Policies of the Company's Annual Report on Form 10-K for the fiscal year ended January 31, 2015, the Company recognizes goodwill as the excess cost of an acquired business over the net amount assigned to assets acquired and liabilities assumed.

The reporting unit's fair value was estimated based on discounted cash flows and that fair value amount was compared to the carrying value of the reporting unit. This analysis indicated that the estimated fair value of the Engineered Films reporting unit exceeded the net book value by approximately $50,700 or 37.2%. No significant changes were noted in the market conditions in fiscal 2016 third quarter and operating income was consistent with expectations at the end of second quarter. Although oil prices continue to be lower and sales are down, the profitability of the division continues to be higher than the trailing months at the time of the impairment analysis given the lower material costs in comparison to the selling price. As such, the Company concluded a triggering event did not occur in the current quarter for Engineered Films.

In the fiscal 2016 third quarter the Company determined that a triggering event occurred for its Vista reporting unit, a subsidiary of the Aerostar Division. In addition to the Company making a change in the executive leadership of the Vista reporting unit during the quarter, financial expectations for sales and operating income of the reporting unit were lowered due to delays and uncertainties regarding the reporting unit’s pursuit of large international opportunities, one of which was expected to be awarded during the current quarter. While Vista has been in the process of negotiating a large international contract, the contract did not materialize in the fiscal 2016 third quarter as expected. The likelihood of being awarded this or other such contracts in the next twelve months is now lower than it was in the second quarter. The Company continues to pursue these international opportunities, but the timing of any contract award is less certain. As a result of a delay in being awarded this large international contract, the Company lowered its financial forecast for the business. As a result of these factors, the Company performed a Step 1 impairment analysis using fair value techniques as of October 31, 2015 for both long-lived assets and goodwill.

As described in Note 7 Goodwill and Long-lived Asset Impairment Loss and Other Charges, the Company concluded that the Vista goodwill balance was fully impaired and that certain long-lived assets of the Vista reporting unit, including finite-lived intangible assets, were impaired as of October 31, 2015.

Although the profitability of the Company’s other two reporting units, Aerostar (all operations other than Vista) and Applied Technology, has been down as compared to the prior year, the Company identified no triggering events requiring a Step 1 goodwill impairment analysis or long-lived asset impairment test for either of these reporting units. The Company will conduct its planned annual assessment of goodwill for impairment in the fourth quarter.

There have been no material changes to the Company's significant accounting policies as described in the Company's Annual Report on Form 10-K for the fiscal year ended January 31, 2015.
