Advanced Techniques in Resealable Packaging

Flexible resealable packages for food products that provide improved accessibility to the contents. The packages have a resealable access opening with expanded sections that extend outward from the main cut. This allows easier removal of products without getting caught in the film. A starter portion lifts the sealing layer and flap. An integrity feature ruptures after opening to indicate if the package has been opened before. The cuts have terminations to prevent further tearing.

Breathable packaging for food products like fruits and vegetables that extends shelf life by optimizing the internal atmosphere. The packaging has resealable peelable films with perforations to allow gas exchange. This promotes controlled atmospheres inside the package that extend food quality and prevent spoilage. The perforations allow transmission of gases like CO2 and O2 based on the produce respiration rate. This prevents premature fermentation and maintains freshness during storage. The resealable films also allow repeated access to the food.

Packaging for food products like leafy greens that improves freshness and automates packing. The packaging has two layers of material that enclose the food inside. The first layer is fixed to the container base and the second layer is removably sealed over it. This allows the food to be placed in the container through the first layer, which is then sealed by the second layer. The two-layer design prevents air from reaching the food and extends freshness. It also facilitates automated packing by allowing the food to be arranged in the first layer and then sealing with the second layer.

A package design with reusable seals that can be repeatedly opened and closed without sticking or contamination. The package has two adhesive parts that can be brought together to seal the opening. The key characteristic is that the adhesion force between the parts is balanced with properties that prevent sticking. The 90-degree peel force between the parts when sealed is 0.02 N or more, and the dynamic friction and tack force of each part are 1.50 or less and 1.60 N or less, respectively. This allows good sealing while preventing material adhesion.
