“…95 Alternatively, the esterified hydrophobic layer could then be sprayed with a thin layer of beeswax, which could lead to better adherence of the coating to the surface due to the similarities in hydrophobicity. 96,97 Utilizing multiple modification strategies at once also introduces multiple tunable variables, such as beeswax coating thickness or crosslinking extent, which should introduce finer control of nutrient release kinetics. These multiply-modified beads warrant further research.…”

“…Additionally, NaNO 2 must be in an acidic environment to react and become a nitrosating agent ( Figure 8 b Side reaction) [ 47 ]. However, TMTD and ZDEC are still used as accelerators in latex products and in the research of new rubber products [ 48 , 49 , 50 , 51 ]. Moreover, zinc diethyldithiocarbamate, a disulfiram metabolite, exhibits robust anti-cancer activity in vitro, potentially through mechanisms linked to its role in disulfiram’s anti-alcoholism action [ 52 ].…”

Common kitchen wraps like plastic and aluminum foil create significant environmental burdens. Plastic wrap, typically made from non-renewable fossil fuels, often ends up in landfills for centuries, breaking down into harmful microplastics. Aluminum foil, while effective, requires a large amount of energy to produce, and recycling it at home can be impractical due to food residue. A promising new alternative, low-nitrosamine rubber wrap film, aims to reduce waste by offering a reusable option compared to traditional single-use plastic wrap. The film is environmentally friendly, durable, and effective in sealing containers and keeping food fresh or crispy. The raw materials used to make the product were studied, namely fresh and concentrated natural rubber latex. No nitrosamines were found in either the fresh or concentrated latex, which is important as nitrosamines are known to be carcinogenic. The absence of nitrosamines in the raw materials suggests that the universal rubber wrap film is safe for use. In this study, the rubber formulation and properties of rubber used to make rubber wrap film were studied. The content of additives affecting the rubber properties was varied to find the optimum rubber formulation for making rubber wrap films. The rubber formulation with the least amount of chemicals that met the following criteria was selected: tensile strength of at least 15 MPa, elongation at break of at least 600%, and nitrosamine content below 6 ppm. It was found experimentally that the optimum rubber formulation for making a translucent rubber film had 0.7 phr zinc oxide and 1.0 phr sulfur. Performance tests revealed the rubber wrap film’s superior sealing capabilities. Its elasticity allows for a tighter fit on containers, effectively conforming to various shapes and creating an optimal seal compared to plastic wrap and aluminum foil. The results of this study provide valuable information for developing a universal rubber wrap film that is safe with low nitrosamines.

The rubber wrap film is a promising new product that could have a positive impact on the en-vironment. The film is environmentally friendly, durable, and effective in sealing containers and keeping food fresh or crispy. The raw materials used to make the product were studied, namely fresh and concentrated natural rubber latex. No nitrosamines were found in either fresh or concentrated latex, which is important as nitrosamines are known to be carcinogenic. The absence of nitrosamines in the raw materials suggests that the universal rubber wrap film is safe for use. In this study, the rubber formulation and properties of rubber used to make rubber wrap film were studied. The content of additives affecting rubber properties was varied to find the optimum rubber formulation for making rubber wrap film. The rubber formulation with the least amount of chemicals that met the following criteria was selected: tensile strength at least 15 MPa, elongation at break at least 600%, and nitrosamine content below 6 ppm. It was found experimentally that the optimum rubber formulation for making a translucent rubber film had 0.7 phr zinc oxide and 1.0 phr sulfur. In actual use tests it was found that the translucent rubber wrap sealed containers more tightly than a PE plastic film or aluminum foil, because of its elasticity. This allows the rubber film to conform to the shape of the container more closely, creating a tighter seal. The results of this study provide valuable information for developing a universal rubber wrap film that is safe with low nitrosamines.
