“…During heat sealing process, the surface of films underwent melting via applied heat. This could promote the interfacial interactions across the contact surfaces, thus yielding the sufficient seal strength to the sealed film . From Table , the sealing strength were increased first and then declined with the addition of PBAT.…”

Blown films of poly(lactic acid) (PLA)/poly(butylene adipate‐co‐terephthalate) (PBAT) blends were prepared, bis(tert‐butyl dioxy isopropyl) benzene (BIBP) as crosslinking agent. From wide‐angle X‐ray diffraction results, PLA/PBAT/BIBP involved all the diffraction peaks were consistent with PLA and PBAT. For the DSC curves of PLA/PBAT/BIBP films, there were two glass transition temperature and two melt temperature, there existed two step decomposition in the thermogravimetric curves. Both Han plots and Cole–Cole plots indicated high homogeneity of the 40/60/0.1 PLA/PBAT/BIBP blend. SEM micrographs of the films revealed more ductile deformation with increasing PBAT content and 40/60/0.1 sample had better miscible compared with others. For the PLA/PBAT/BIBP films, tensile tests indicated that the elongation at break were increased with increasing PBAT content and the values of the tensile strength in the machine direction were higher than those in the transverse direction. The addition of PBAT, enhanced the toughness of the PLA/PBAT/BIBP films. From tear test and heat sealing test, the 40/60/0.1 PLA/PBAT/BIBP film exhibited the highest tear strength and the highest sealing strength among all the samples. POLYM. ENG.

“…The T g of the OSG film was 167.84 °C, whereas T m and Δ H f were not detected. In general, the T g of fish skin gelatin is about 81 °C (Tongnuanchan and others ). This difference in T g values might be explained by the difference in film preparation and the mobility of the gelatin chain (Molinaro and others ).…”

Olive flounder skin gelatin (OSG) was used as a film base material. A bilayer film of OSG and polylactic acid (PLA) was prepared using solvent casting method to enhance the film properties. Physical properties of the OSG-PLA film were increased compared with the nonaugmented OSG film. In particular, the PLA lamination decreased water vapor permeability from 2.17 to 0.92 × 10 g·m/m ·s·Pa, as well as of the water solubility from 16.62% to 9.27%, in the bilayer film relative to the OSG film. The oxygen permeability of the OSG-PLA bilayer film was held low by the OSG film, compensating for the high oxygen permeability of the PLA layer. Therefore, the OSG-PLA bilayer film with its enhanced physical properties and high water and oxygen barrier properties can be applied as a food packaging material.

“…In general the seal strength of a heat sealed flexible pouch may vary, and can depend on the types of materials used for the sealing layer, the seal temperature, dwell time and pressure of the sealing jaw [1][2]. Since seal strength is one of the most important quality characteristics for evaluating packaging performance, researchers have attempted to analyze the seal strength of flexible packaging by varying packaging materials or sealing parameters by using standard testing procedures [3][4][5][6][7][8][9][10].…”

ABSTRACT:The seal strength of flexible packaging indicates both functional performance and the ease of opening. This research aims to compare the seal peeling mechanisms evaluated by human participants and standard machine tests. The tests were conducted on flexible films used for typical packaging applications, LDPE, LLDPE and Nylon/LLDPE. Human peeling was simulated through the use of novel force measurement equipment. The results showed that the maximum machine peel force set by standard test methods was generally lower than the human peel force for most sealing temperatures. In all film types no significant difference was shown between genders although for people over 65 years peel force was generally lower than for the younger cohort. The results also indicated that peeling speed of human participants was normally higher than the peeling speed set according to the machine test standard.
