Flat Bottom Pouch with a tear-off tab
Product Description
Material & Barrier Properties
1.Barrier Layer Materials and Moisture and Oxidation Protection
Multi-layer composite structure: This packaging is a typical composite bag for dry pet food and typically features a multi-layer structure such as PET/VMPET/PE
Outer Layer (PET): Provides a printing substrate with good stiffness, flatness, and high print clarity.
Middle Barrier Layer (VMPET): Blocks the passage of light (light-blocking), oxygen, and water vapor, preventing the oxidation and spoilage of fats in grains as well as the inactivation of probiotics.
Inner Layer (PE): Provides excellent heat-sealing performance and food-grade contact safety.
2.Freshness Preservation and Secondary Sealing Mechanism
Embedded Resealable Zipper: The top closure features a snap-type zipper. After tearing open the easy-tear tab for the first time, consumers can repeatedly open and close the zipper to minimize the frequency of contact between the contents and air, thereby preventing caking and insect infestation.
Packaging Structural Engineering
1.Flat-Bottom Vertical Support
l Bottom Sealing and Upright Stability: Unlike traditional “stand-up pouches ” which rely on an inward fold at the bottom for support, the flat bottom pouch features a completely flat rectangular base. This physical structure ensures that the package maintains a square shape and optimal center of gravity after filling, allowing it to stand upright and stable without tipping over or tilting, even when filled with heavier grains weighing 420g.
2.Side Gussets and Space Utilization
l Three-Dimensional Expansion: The gussets on both sides provide ample three-dimensional expansion space inside, allowing the front dimensions of the packaging to remain compact while maintaining the same capacity. This significantly improves space utilization during shelf stacking and transport packaging.
3.User-friendly, easy-to-open design
Mechanically Pre-Cut Tear Notch: Precisely punched tear notches are located at the bottom of both sides of the seal, allowing consumers to tear the package cleanly along the pre-set stress lines without the need for scissorsPrinting & Surface Treatment
1.Matte Finish Surface Treatment Process
l Anti-Glare and Textured Finish: The outermost layer of the film features a matte finish (MOPP or matte ink), which effectively eliminates glare from strong lighting, making the packaging’s content clearer and more legible under retail lighting while giving the packaging a more textured feel.
2.Five-Side Printing and Underprinting Technology
l Visual Coverage of Blind Spots: The octagonal seal structure creates five distinct printing areas: the front, back, left and right sides, and the bottom. This design specifically utilizes the bottom printing area to extend the brand logo and background color to the bottom, thereby addressing the issue of “visual blind spots” or “white backgrounds” that consumers see when looking up at traditional packaging placed on higher shelves.
Customization Available
This stand up pouch offers full customization, allowing for a combination of glossy and matte finishes to create a visually rich, layered effect. The pouch dimensions, hanging hole placement, and stand-up bottom structure can all be adjusted as needed. Brand graphics and color schemes can be custom-printed. Additionally, the composite materials and barrier properties can be tailored to meet product freshness requirements, making it suitable for a wide range of snack food packaging needs.
