Custom Recyclable Flat-Bottom Bags
Recyclable Flat-Bottom Bags
Flat-bottom pouches are a highly favored packaging format known for their excellent stability and ability to stand upright on shelves. YPAK uses high-quality mono-material PE (polyethylene) to produce recyclable flat-bottom pouches. This solution is ideal for brands that want to appeal to eco-conscious consumers. We construct recyclable pouches entirely from 100% mono PE, typically using three to four-layer films that provide both durability and essential barrier protection, often enhanced with an EVOH coating for superior oxygen resistance.
As one of the leading manufacturers of recyclable flat-bottom bags in China, we efficiently handle high-volume orders at competitive prices, supported by our strategic location near major raw material suppliers. Our recyclable mono-PE films can be sourced daily, and our in-house, fully automated production lines ensure consistency and scale.

Offered in a variety of sizes, recyclable flat-bottom pouches are flexible enough to satisfy product packaging needs, therefore providing a more sustainable replacement for traditional packaging types.
Advanced Recyclable Materials for Your Flat Bottom Bags
Mono-Material LDPE Systems- Recyclable Flat-Bottom Bags
We build our recyclable flat-bottom bags using 100% LDPE(Low-Density Polyethylene), a type of PE (Polyethylene) that’s soft, flexible, and compatible with #4 soft plastic recycling streams, enabling a closed-loop system. We design co-extruded PE layers with excellent barrier and heat-seal characteristics.
Co-extruding layers of LDPE-based film structures provides:
Effective oxygen and moisture barrier properties (comparable to traditional multi-material laminates)
Reliable heat-seal performance
This design keeps end-of-life recyclability intact while maintaining the protective functionality needed for high-quality food and coffee packaging.
Designed for your brand's packaging needs, every choice is modifiable in terms of barrier strength, printability, and thickness.


Recyclable Flat-Bottom Bags Structural & Design Engineering
Our product engineers configure every element of the recyclable flat-bottom bag:
Customized Footprints: From compact, single-serving snack formats to large-format bags for bulk items like coffee or pet food, our bags’ dimensions are precisely calculated to the product's volume and density, eliminating unnecessary material usage.
Material Science for Recyclability: Our engineering solution lies in creating multi-layer films that provide the necessary barrier properties (against oxygen, moisture, and light) while being compatible with existing recycling systems.
Mono-Material Laminates: The industry is rapidly moving away from traditional multi-material laminates (e.g., PET/Alu/PE), which are difficult to recycle. To meet the market’s demand, YPAK crafts mono-material laminates, typically based on polyethylene (PE) or polypropylene (PP). These structures consist of multiple layers of the same polymer family, sometimes with different densities or orientations, to achieve your desired performance characteristics.
Advanced Barrier Coatings: To replace non-recyclable layers like aluminum foil and metallized films, our engineers utilize ultra-thin, high-performance barrier coatings. These are often silicon oxide (SiOx) or aluminum oxide (AlOx) based, applied in a transparent layer that is so minimal it doesn't contaminate your bag’s recycling stream.
Recyclable Adhesives: The adhesives used to laminate the film layers are also being re-engineered. We consistently design new formulations to be compatible with the primary polymer, ensuring that your entire package can be processed as a single material.
Integrating Functionality with Recyclability in Mind for Flat-Bottom Bags
The true test of a well-engineered recyclable bag is its ability to incorporate convenient features without compromising its end-of-life recyclability function.
WIPF Degassing Valves: These are essential for products like freshly roasted coffee that release carbon dioxide. We offer an option to add WIPF degassing valves on your flat-bottom pouches that are available in recyclable and compostable versions. These one-way valves are typically made from the same polymer as the bag (e.g., PE or PP), allowing for seamless integration and recycling. The engineering focus is on the precise location of the valve for optimal degassing and the compression type, which can be tailored to the specific product and filling process.
Resealability:

○ Slider-Free and Pocket Zippers: To avoid the use of mixed materials often found in conventional sliders, we have shifted our focus to press-to-close zippers. "Slider-free" zippers are integrated into the bag's film and are made from the same recyclable polymer.
○ "Pocket zippers" offer a unique solution where the zipper is shielded by a flap of the flat-bottom bag's material, preventing product from clogging the tracks and ensuring a reliable seal. The engineering of these zippers involves intricate die-cutting and heat-sealing processes to create a user-friendly and robust closure.
○ Recyclable Tin-Ties: Tin-ties are a popular choice for a classic premium feel. Our sustainable options now feature paper-based ties or those designed to be easily removable by the consumer before recycling. We carefully select the adhesive used to attach the tie so as not to interfere with the recycling process of the flat-bottom pouch.
Micro-Perforations and Easy-Tear Features: Laser-scored micro-perforations offer a clean and convenient way for consumers to open the package. Our technology allows for precise control over the tear initiation and propagation, eliminating the need for tear notches that can sometimes create small, loose plastic pieces. The perforations are engineered to maintain the package's barrier integrity until it is intentionally opened.

Efficiency and Visual Distinction:
○ Rounded Corners: Beyond aesthetics, rounded corners provide a more comfortable and ergonomic feel in the hand. This seemingly simple feature requires precise die-cutting and sealing to ensure the corners are strong and do not become weak points in the package.
○ Die-Cut Windows: Offering a glimpse of the product inside is a powerful marketing tool. In recyclable bags, these windows are not a separate plastic film but rather a transparent section of the bag's mono-material structure. Our engineers maintain the barrier properties of the window area, often through the application of the aforementioned clear barrier coatings.
These options offer your brand full control to design recyclable flat-bottom bags aligned with product protection and user experience goals.
Print & Finish Customization for Your Recyclable Flat-Bottom Bags
Visual branding is as important as function. Our recyclable flat-bottom bags can help your brand stand out through:
Digital Printing: This is perfect for small batches, seasonal offerings, and product test launches.
Rotogravure Printing: Deliver Vibrant designs, high-resolution graphics. Compatible with mono-material films when using recyclable-grade inks.
Surface finishes: Choose subtle, recyclable-friendly options like embossing to add texture without added materials.
You decide how your recyclable flat-bottom bag looks, feels, and connects, while retaining recyclability.
