Provided are methods and compositions for improving storage and/or transportation of food, flowers, plants, or the like by coating of the same with silk proteins or other substances including silk fibroin, chitin, acetylated monoglycerides, shellac, starch, high fructose corn syrup, mayauba wax, maydelilla wax, beeswax, vegetable oil, paraffin oil, ethylenediaminetetraacetic acid, cellulose, pectin, alginate, chitosan, gum Arabic, soy protein, zein, casein, and/or whey.

Maintenance of conditions optimal to perishable materials within a package during shipment will prolong the lifetime of the goods for shipment. The present invention provides a system for mitigating spoilage of perishable materials. The system comprises a container defining a compartment for storage of perishable materials, the container further defining an opening for providing communication between the compartment and an outside environment. A film cooperates with the container to seal the opening of the container and control flow of gas and water vapor transfer between the compartment and the outside environment.

Provided is a production method for a freshness-keeping bag capable of reducing the inflow of oxygen from the outside of the bag to a very low level, and thereby keeping the freshness of a content thereof for a long period of time. The present invention provides a method for producing a freshness-keeping bag formed of a film, wherein the freshness-keeping bag has a band-shaped joining region in which two ends of the film are overlapped and joined together, the joining region comprising a plurality of joined parts in which the two ends of the film are joined together, and a non-joined part which is located between adjacent ones of the joined parts and in which the overlapped ends of the film are not joined together, the non-joined part composing a non-linear ventilation passage communicating between an internal space of the bag and the outside of the bag, the method comprising the step of forming the joined parts by ultrasonic welding, wherein the step of forming the joined parts includes continuously forming the joined parts in the film, while rotating a disk-shaped ultrasonic welding anvil with respect to the film, wherein the ultrasonic welding anvil has a plurality of protrusions formed on an outer periphery thereof continuously at given intervals and correspondingly to the configuration of the joined parts of the bag.

A stem bayonet clip having a compression portion with opposing main body portions movable with respect to one another; which may include one or more compression ribs provided on interior surfaces of the opposing main body portions; a locking mechanism provided about an edge portion of the opposing main body portions, the locking mechanism being configured to retain a compressive force applied to a stem of a floral element inserted between the opposing main body portions; and a bayonet portion configured to be inserted into floral foam or similar material. The stem bayonet clip configured to grip the stem portion of a flower while the bayonet portion holds the flower in place (in floral foam) as part of a flower arrangement.

Plastic grid or framework arrangements are used to support and position of bowls that hold flower arrangements, candles, letters, and other decorative elements. These grids are deployable in water fountains, indoor and outdoor pools, and other small bodies of water during festive occasions or for longer term decorative display. The grid themselves do not float, and are positioned below the surface of the water, and thus are not readily visible. Buoyancy is provided at the hubs that form nodes in the grids. The hubs also support floating bowls containing various decorative elements. The resulting effect is that the various decorative elements appear to be floating on the surface while the sub-surface grid structure maintains their relative positioning, keeping the bowls from clumping together at the edges or in the corners of the pool or fountain.

A binding wrap for maintaining the hydration of cut flowers is disclosed. The wrap is formed by folding a flexible, absorbent sheet over and around the stems of cut flowers. An assembly of a bouquet of cut flowers with a flexible, absorbent binding wrap folded around its stems is also disclosed as is a method of forming such a wrap.

The present invention relates to the use of a sheet for extending shelf-life of biological products, wherein the sheet comprises or consists of a thermoplastic composition with a hydrophobic polymer phase comprising at least one hydrophobic polymer; a hydrophilic polymer phase comprising at least one hydrophilic polymer; and optionally at least one compatibiliser.

Described is a packaging, and method and system for packaging an individual and single serving of plant matter, such as a cannabis flower. Also described are a method of making and using for the packaging.

A method and means for releasing a terpene mixture to a Cannabis flower during storage with may be from a cotton pulp card or a two-way humidity pack with an additional terpene blend for keeping a Cannabis flower fresh while naturally increasing the desired terpene levels. The product is a blend of humidity regulating agents infused with terpenes (plant derived) which allows for the product to be paired with herbal material to increase and maintain the relative humidity, while transferring the flavor/aroma/taste terpenes from the package into the herbal material. There are two embodiments, the first is a Terp Pack+Humidity (“Terp Pack+RH”) which contains a herban material to increase and maintain relative humidity, while releasing the infused terenes, and the second is more simply a Terp Pack (“Terp Pack”) which contains no humidity enhancing material and is only a carrier for releasing the terpene mixture.
