Concerns in food safety and the need for high-quality foods have increased the demand for extending the shelf life of packaged foods. Subsequently, promoting and investigating the development of antibacterial materials for food packaging has become inevitable. Zinc oxide nanoparticles have attracted attention lately owing to their multifunctional properties, especially antibacterial activity. For this study, antibacterial low-density polyethylene films were prepared by coating zinc oxide nanoparticles onto their surface. The low-density polyethylene film antibacterial activity was evaluated toward Gram-positive and Gram-negative bacteria. The scanning electron microscopy images showed that using anhydride-modified low-density polyethylene (LDPE-g-AM) resin permitted improved zinc oxide nanoparticle distribution on the low-density polyethylene film surface, reduced the agglomerate sizes, and reinforced the zinc oxide nanoparticle bonding to the low-density polyethylene film surface. We found that the coated low-density polyethylene films exhibited high antibacterial activity against both strains. The antibacterial tests also proved that the coated films retained their antibacterial efficiency toward Escherichia coli, even after eight months, with a reduction rate higher than 99.9%, whereas for Staphylococcus aureus the antibacterial properties for the linear low-density polyethylene (LLDPE) films decreased at eight months and improved for the LDPE-g-AM films. When the zinc oxide coated films were laminated with neat low-density polyethylene, only the LDPE-g-AM was still active against E. coli provided that the lamination thickness does not go beyond 8 µm. This research demonstrated that the coated low-density polyethylene films have excellent attributes when used as an active coating in the food packaging industry.

Six ratios of nanosilica particles were employed to fabricate low-density polyethylene (LDPE) composites using melt mixing and hot molding methods. Several composite films with different ratios (0.5, 1, 2.5, 5, 7.5, and 10 wt%) of SiO2 were prepared. The obtained composite films were identified and characterized by Fourier-transform infrared spectroscopy (FTIR) and ultraviolet-visible spectroscopy (UV-VIS). At a specific mixing ratio, far infrared radiation transmittance was prohibited while the ultraviolet-visible transmittance is allowed; this will be explained in detail. Optical measurements show that the composite films prevent the transmission of IR radiation near 9 μm and allow UV-VIS transmission during sun-shining time. The mechanical behaviour of a nanosilica-reinforced LDPE composite was studied using tensile tests. The addition of 1 wt% nanosilica has successfully enhanced the mechanical properties of the LDPE material.

Abstract Degradable native low density polyethylene (LDPE) and modified LDPE films containing 5–30 wt% of sago starch, and LDPE with prodegradant additives in the form of a master batch (MB) in the amounts of 30% starch were prepared by twin screw extrusion followed by injection molding. Studies on their mechanical properties such as tensile strength and elongation at break and biodegradation were carried out by tensile test and exposure to hydrolysis, fungi environment as well as by natural weathering and burial in soil. The presence of high starch contents had an adverse effect on the tensile properties of the blend films. High starch content was also found to increase the rate of biodegradability of the films. The characteristic parameters of the environment were measured during the period of degradation and their influence on degradation of LDPE was discussed. Changes in weight, morphology, thermogravimetric analysis (TGA) and tensile properties of polymer samples were tested during the experiment performed.

Antimicrobial coated films were produced by an innovative method that allowed surface modification of commercial low-density polyethylene films so that well-defined antimicrobial surfaces could be prepared. A Pluronic™ surfactant and a polystyrene-polyethylene oxide block copolymer were employed to develop modified materials. The Pluronic™ surfactant provided a more readily functionalised film surface, while block copolymer provided a reactive interface which was important in providing a route to silver nanoparticles that were well adhered to the surface. Antimicrobial films containing silver were manufactured using a spray coater and the amount of silver used for coating purposes varied by the concentration of the silver precursor (silver nitrate) or the number of silver coatings applied. Potential antimicrobial activity of manufactured silver-coated low-density polyethylene films was tested against Pseudomonas fluorescens, Staphylococcus aureus and microflora isolated from raw chicken. The microbiological and physicochemical quality of chicken breast fillets wrapped with silver-coated low-density polyethylene films followed by vacuum skin packaging was also assessed during storage. Antimicrobial activity of developed silver-coated low-density polyethylene films was dependent ( p < 0.05) upon the concentrations of silver precursor and the number of silver coatings used. Better antimicrobial activity against P. fluorescens, S. aureus and chicken microflora was observed when the concentration of silver precursor was 3% and the spray coating deposition of silver was repeated four times. Use of silver-coated low-density polyethylene films extended ( p < 0.05) shelf life of chicken breast fillets and enhanced ( p < 0.05) oxidative stability compared to control films. Results indicated that silver-coated low-density polyethylene films could potentially be used as antimicrobial packaging for food applications.

Polyethylene waste contamination is one of the most concerning environmental issues not only in India but also in world. Microbial degradation is one of the safest and environment friendly process to degrade polyethylene among other major types degradation methods such as thermo-oxidative degradation and photo-degradation. The present research focused on the isolation, enrichment, and characterization of polyethylene-utilizing bacteria, not screen as far for biodegradation, and evaluation of its degrading capacity on polyethylene. A bacterial strain (TN2) was isolated from a motor-oil contaminated soil. The biochemical characterization of the strain was based on an automated microbial identification system. Strain TN2 was identified through 16SrRNA gene sequencing, which shows strain was closely related to Microbacterium genus and identified as Microbacterium barkeri SH20 (Accession No. KY887791.1). To examine the degradation capacity of isolated strain, it was used for biodegradation studies on two types of polyethylene films i.e. LDPE as well as HDPE (low and high density polyethylene respectively) HDPE (high-density polyethylene) for 30 days. The film samples were analyzed after bacterial strain incubation based on the weight loss percentage and the Keto & Ester Carbonyl Index (via Fourier transform infrared spectroscopy- FTIR). The highest decrease in weight loss percentage was calculated of PE-S1 HDPE film samples i.e 0.985±0.23%, as weight loss represents a qualitative evaluation of biodegradation. FTIR studies shows changes IR peaks of C=O regions and Keto & Ester Carbonyl Index was found to decrease in HDPE films (PE-S1) compared to other two LDPE (PE-S2) and HDPE films (PE-S3) shows degradation of polyethylene. The research established that Microbacterium barkeri SH20 (TN2) is a novel bacterial strain that can degrade polyethylene films. Hence, it can be used in future biodegradation studies and field trails.

The trade-off between breathability and strength properties has (grudgingly) been accepted by producers of microvoided film, such as for diaper backsheet. The key resin, additive, film fabrication, and film stretching parameters that impact moisture vapor transmission as well as the physical attributes of the film have been identified. The understanding of these complex interactions provided the basis for modification of the polyethylene (PE) molecular architecture that promotes both high MVTR and high-strength properties in microvoided films. This information has resulted in new polyethylene resins for the breathable film market.

Environmental concerns are now driving additive suppliers and polymer resin manufacturers to step up efforts to create innovative materials for the future. In the present work, a “biodegradable” additive/promoter was incorporated into a butene-based linear low density polyethylene (LLDPE) at different levels. The properties of the blown films derived therefrom were investigated. In the first step the “degradation additive/promoter” was converted into a 50% masterbatch in LLDPE. In the second step, this concentrate was let down at 5, 10, 15 and 20% level in a butene-based film grade LLDPE. The properties of the films were characterized. In the third step, the films were subjected to “real-time” degradation tests; using natural soil and under vermicompost conditions. Films subjected to degradation under vermicompost conditions have shown encouraging results. After 3 months, the films containing 15 and 20% additive were found to have disintegrated to a practically unusable form.

The phase content of a low-density polyethylene was studied by analysis of the CH2 rocking vibrations in non-oriented films prepared from the press (P-films) or from solution (S-films). Spectral simulations of the transmission spectra give the mass fractions of the orthorhombic phase αortho and of two noncrystalline phases (monoclinic-like and amorphous). The values of αortho (IR) are compared to αortho (i) where (i) stands for the X-ray diffraction, density, and DSC techniques. New results are obtained concerning the orthorhombic order and the change of phase content with aging. A two-phase analysis is justified for non-aged films containing a small amount of the monoclinic-like phase. The values of αortho (IR) are larger than αortho (i), the difference ranging between 0.12 and 0.43. The difference is a measure of the short-range order. αortho (IR) can reach 0.73 for the S-films. The stability of the short-range order phase is investigated. The sample is also analyzed using the trace of slow calorimetry. The difference between αortho by DSC and by slow calorimetry is a measure of strainable order. During aging, the variation in the phase content is large for the noncrystalline phases (in content and frequency) and small for the orthorhombic. The increase of the monoclinic-like phase during aging suggests that it is a precursor of the more stable orthorhombic organization. The quantification of two noncrystalline phases on fresh and aged films clarifies some ambiguity found in the literature about the monoclinic-like phase and the localization of bands in the rocking region for sample characterization. Analysis of other regions of the spectrum is needed to confirm the present results. Key words: low-density PE, phase content, FTIR, network phase, slow calorimetry.

In this work Graphene nanoplatelets (GNPs) filled with Linear low-density polyethylene (LLDPE), nanocomposite films designated as LLDPE+1%GNP and LLDPE+5% GNP were manufactured using LLDPE pristine granules, 1 wt. % GNPs-LLDPE, and 5wt. % GNPs-LLDPE masterbatch granules by the extrusion-blow molding process. It was found that the ductile behaviour of neat LLDPE film and nanocomposite films are anisotropic in the machine direction (MD) and transverse direction (TD). The tensile strength of neat LLDPE films in the MD and TD is 25.93 & 20MPa. LLDPE+1GNPs nanocomposite films showed higher tensile strength in the MD and TD 28.38 & 23MPa, and LLDPE+5GNPs nanocomposite films showed 24.36 & 23MPa respectively. The high concentration of GNPs in LLDPE acts as plasticizers increased the elongation, reduced the strength, and increased the rate of thermal degradation. The XRD results reveal additional peeks observed in LLDPE+5GNPs nanocomposite films infer the slight change in crystallinity as compared to neat LLDPE film. This is evident in the change of tensile behaviour of nanocomposite as compared to LLDPE.

Surface modification of low-density polyethylene (LDPE) films was carried out via a novel photografting polymerization technique with acrylamide (AAm) as the monomer. The photografting polymerization can be achieved via one-step method and two-step method. The photografting polymerization reactivity of AAm was examined with benzophenone (BP) as the photoinitiator and low-density polyethylene (LDPE) film as the substrate with “sandwich” assembly. Moreover, the occurrence and evolution of grafting polymerization of AAm on the substrate was demonstrated XPS analysis and SEM pictures.

Guar gum hydrogels may be dried to form polymer films which have the potential for use as biodegradable alternatives to polymers such as low-density polyethylene. In this study, the tensile strength and tensile modulus of guar gel films having moisture contents ranging between 15% and 18% (wet basis) were measured at a strain rate of 1 mm min−1. Mean tensile strengths of the films ranged between 25 MPa and 40 MPa (dependent on composition) which is of similar magnitude to the tensile strength data for polyethylene and cellophane that are reported in the literature. The mean tensile modulus of the films (1.5–2.5 GPa) was higher than the tensile modulus values reported for low-density polyethylene but comparable to those for cellophane (3 GPa).
