Antimicrobial Solutions for Package Protection

Packaging wet pulp like cellulose in a way that reduces corrosion and mold growth while avoiding the need for large amounts of preservatives. The method involves treating the pulp slurry with a preservative, dewatering it to form a wet pulp lump, degassing the lump in a sealed bag, and sealing the bag to create a packaged wet pulp. The degassing step removes air from the bag to reduce pressure inside. This prevents oxygen-based corrosion and mold growth without using high preservative levels. The packaged wet pulp can then be stored without further drying.

Environmentally friendly packaging material that is biodegradable and/or recyclable. The packaging has a carrier substrate with coating layers. The coating layers are applied in a specific sequence: first coating, second coating directly on the first, and optionally a third coating indirectly on the second. The coating layers contain binders, pigments, and additives like polysaccharides, surfactants, and preservatives. The carrier substrate can be made of cellulose fibers. The coating layers have specific weight percentages of components. The packaging material can be produced using specific coating colors with viscosities suitable for industrial machines. The packaging meets standards like EN 1186 for food safety.

Carbon dioxide-releasing pad for food packaging that can actively change the gas composition inside food packages to inhibit spoilage and extend freshness. The pad contains a carbon dioxide-releasing filling made of sodium bicarbonate, organic acids, and moisture receptors. The acids trigger carbon dioxide emission when they come into contact with the bicarbonate. The moisture receptors supply water to the bicarbonate to further enhance carbon dioxide release. This pad can be inserted into food packages to emit carbon dioxide and displace oxygen, suppressing microbial growth and preventing spoilage.

Paper packaging for food that provides both odor control and antimicrobial properties. The packaging uses a coating layer applied to kraft paper. The coating contains extracts from cypress, lemon, burdock, green tea, ginkgo, and basil, along with complex inorganic materials, fragrance, binder, dispersant, and solvent. The coating provides simultaneous odor masking and antibacterial performance for food packaging.

Bag for packaging fruits and vegetables that prevents mold growth and spoilage without sacrificing visibility of the contents. The bag has a first region made of a polylactic acid (PLA) film and a second region made of a paper sheet. The paper sheet can be a laminate with a resin layer. The paper sheet basis weight is 100 g/m2 or less. The PLA film density is 1.0 g/cm3. The regions are bonded by heat sealing or an adhesive. This configuration using PLA film and paper inhibits mold growth better than just PLA film alone. The paper prevents mold while allowing visibility.

A food packaging box designed to hold and protect food items during transport and storage. The packaging box is specifically designed for food applications and aims to provide optimal protection and preservation of the food inside. The box may feature features like reinforced corners, shock-absorbing materials, ventilation holes, and sealable closures to prevent moisture and contaminants from entering. The goal is to create a food packaging box that ensures food safety, freshness, and quality during transportation and storage.

A natural spray solution to increase the shelf life of chicken meat without using chemicals or preservatives. The solution contains chitosan, lactic acid, glycerol, vitamin C, and vitamin D dissolved in deionized water. The spray solution is applied to chicken meat to create a barrier that prevents microbial growth and spoilage. The solution is prepared by weighing and mixing the ingredients, homogenizing, filtering, ultrasonicating, sterilizing, and packaging.

Functional reinforcing paper with insect repellent, antibacterial, deodorizing, moisture proofing, and freshness maintaining properties for improved packaging quality. The paper has a coating with a functional material like insect repellent, antibacterial agent, deodorant, freshness retainer, or desiccant. It can also be used as a packaging material itself with contact surfaces containing the functional material. The coating enhances strength, water resistance, and oil resistance.

Biodegradable packaging made from paper impregnated with propolis extract to provide biocidal and antioxidant properties. The paper is treated with water or ethanol extracts of propolis, a natural bee product with antibacterial, antifungal, and antioxidant activity. The impregnated paper can prevent microbial growth on food products during storage. The propolis extracts also have antimold and antifungal effects. The paper packaging degrades faster than regular paper due to the nutrients in propolis enriching the soil. Consumers prefer the propolis paper due to its natural origin and health benefits.

Climate control container for long-term storage of herbs, spices, tobacco, and marijuana that maintains freshness for extended periods like a year or more. The container has two main features: a humidity control arrangement and an air distribution arrangement. The humidity control uses a removable insert element with a permeable bottom and a desiccant chamber between the insert and the container base. This allows moisture to transfer between the herb storage space and the desiccant to maintain stable humidity levels. The air distribution uses a valve assembly to release pressure and prevent damage when opening the container, but also venting to avoid moisture loss. This allows controlling the internal airflow and preventing stale air buildup that can degrade the stored herbs.

Biodegradable nanocomposite food packaging films that provide enhanced antimicrobial and oxidation inhibition properties to prevent spoilage and pathogen growth. The films are made by incorporating biosynthesized zirconium nanoparticles capped with a bioactive compound called Arachisan derived from peanut leaves. The ArZrNPs provide antimicrobial activity against food-borne pathogens like Salmonella and E. coli. They also scavenge free radicals to prevent oxidation. The nanoparticles are dispersed in biodegradable polymer films for sustainable packaging with extended shelf-life and reduced pathogen risk.

Packaged raw amazake with digestive enzymes intact to maintain health benefits and prevent bacterial contamination. The amazake is filled in flexible bags with specific volume (15-50 ml) and Brix (38-42) to avoid temperature differences during heating. The bags are blanched at 55-65°C for a short time to sterilize without inactivating enzymes. Cooling below freezing finishes production. This allows fresh amazake with active enzymes and no bacterial risk.

Separation membrane preservation solution and packaging container for water treatment that prevent degradation of the membranes during storage and use. The preservation solution is an aqueous citric acid solution with a pH of 2.3-3.5. It doesn't cause deformation of the membranes during long-term storage like other preservatives. The packaging container holds the membrane immersed in the citric acid solution to prevent bacterial growth.

Water bottle that allows for hygienic storage of beverages by switching between two containers to prevent bacterial growth in stored drinks. The water bottle has an upper and lower container connected by a switching mechanism. The lower container has a drinking spout and can hold clean beverages. The upper container holds the main drink. The switching mechanism connects or disconnects the containers. When disconnected, the lower container can be used to refill the upper container with a clean beverage. This prevents bacteria growth in the main drink. The switching mechanism also has a straw port to drink without touching the lid. It biases closed to prevent accidental switching.
