Focus of this study is the importance of effort to attain material value conservation, particularly for design of flexible plastic packaging. Inappropriate design of plastic packaging with excessive use of colour and printing ink will be affected to the low acceptance level of plastic waste for recycling. Currently, design criteria of flexible plastic packaging are limited on design for recycling and still not yet fully covered by design for material value conservation. This research aims is to proposed design criteria for material value conservation of flexible plastic packaging using development of design criteria method, confirmatory factor analysis (CFA), and analysis of statistical data using non-parametric statistic multiple correlations, Cronbach's Alpha, to determine that design criteria are valid and reliable. The results found that validation and reliability test for design criteria has been suitable with the Cronbach's Alpha requirement. Recommendation of design criteria consist of; (1) No pigment colour in plastic material, (2) White colour in plastic material, (3) No printing ink in colouration, symbols, pictures, graph and letters on the surfaces of plastic materials, (4) Optimum use of paper label and thin plastic label as informational and promotional purposes of packaging, (5) No adhesive or water-soluble adhesive and non-toxic material, and (6) Recycle-able material with good value and minimum category of the layer used for packaging. Implementation of design criteria for material value conservation of flexible packaging can be as reference to develop the phase of design a flexible plastic packaging product for related stakeholders by constantly widespread that application in industry, region and country.
