Assessment of the quality of food packaging by flexible plastic bags

Abstract

      The packing efficiency of 20 samples (P₁-P₂₀) of food packaged in flexible plastic bags available in the markets of Baghdad was determined in this study, the results indicated that there was no batch number in P₂, P₃, P₄, P₇, P₉, P₁₉ and P₂₀ and it was not clear in P₁. Also, it was note the difference in the validity period of the samples and the non-conformity of others to the validity period in the Iraqi standard specification No. 1847. (2012). as it was 6 month in P₁ and P₂, while it was 24 month in P₅, 12 month in P₁₈ and it was not clear in P₇, but rather it was replaced by the phrase (valid for consumption for a period of five years from the date of production). The results of the welding examination showed the failure of P₃, P₄, P₅, P₁₅, P₁₆ and P₁₇, while the obtained values were 611, 428, 223, 515, 326, 187, 288 and 440 mbar for P₈, P₉, P₁₀, P₁₁, P₁₂, P₁₃, P₁₈ and P₂₀, respectively, while the coating thicknesses were 0.048, 0.096, 0.093, 0.069, 0.088, 0.106, 0.110, 0.487, 0.142, 0.135, 0.136, 0.059, 0.099, 0.113 and 0.081. and 0.083, 0.063, 0.083, 0.127, and 0.094 µm for P₁, P₂, P₃, P₄, P₅, P₆, P₇, P₈, P₉, P₁₀, P₁₁, P₁₂, P₁₃, P₁₄, P₁₅, P₁₆, P₁₇, P₁₈, P₁₉ and P₂₀, respectively
