Stand-up pouches are a type of flexible plastic packaging. They feature folded edges at the bottom or sides, creating a supportive surface after filling, allowing them to stand upright on shelves. This type of packaging often uses composite film materials, processed through printing, dry lamination or extrusion lamination, curing, slitting, and bag making. Common material layers include PET, OPP, NY (PA), PE, and VMPET and AL with metal layers, with different thicknesses and layers selected according to the contents and distribution requirements. Their dimensions are typically designed based on net content and filling equipment parameters, coordinating the layout with barcodes, ingredient lists, nutrition facts, and other information.

1. High Barrier Properties:

Considering the sensitivity of protein powder to moisture and oxygen, a PET/VMPET/NY/PE or PET/AL/NY/RCPP structure is recommended. Typical Oxygen Transmission Rate (OTR) ≤ 1 cm³·m⁻²·day⁻¹, and Water Vapor Transmission Rate (WVTR) ≤ 0.5 g·m⁻²·day⁻¹ (38℃/90%RH). The overall bag thickness is typically between 90–160 μm and can be adjusted based on net content and transport distance to meet shelf-life management and formulation stability requirements.

2. Stability:

The self-supporting bottom structure combined with an 8–10 mm heat-seal width and ≥12 N/15 mm heat-seal strength enhances vertical display stability and drop safety margin. The burst strength of the bag is ≥250 N (instrument method), and the NY layer puncture resistance meets the ≥12 N standard, making it suitable for high-speed bagging and stacking, reducing the impact of bag deformation on appearance and palletizing efficiency.

3. Easy-sealable:

The inner RCPP or PE heat-sealing window is wide, and the linear speed at room temperature can be matched with a 40–80 bpm vertical filling machine. Recommended heat-sealing temperature range is 120–160℃ (PE) or 140–180℃ (RCPP). It offers stable peel strength, and the side seal is flat after cooling and setting, facilitating subsequent labeling and coding. A laser easy-tear line can be configured, with opening force controlled within the 6–10 N range, improving bag opening smoothness.

4. Customizable:

Supports SUP, self-standing bottom, eight-side seal, and flat bottom bag types; common capacity ranges are 100 g, 300 g, 1 kg to 2 kg, and volume can also be calculated based on gram weight and filling density. Material structure can be selected from PET/PE, OPP/VMPET/PE, PET/AL/NY/PE, etc.; window openings, frosted film, and partial glossy lamination can all be customized according to the design and brand style.

5. Fine printing:

Gravure/flexographic printing achieves registration tolerances of ≤0.2 mm, and standard 8–10 color printing ensures clear presentation of formula graphics and nutritional information. Inks and adhesive systems comply with food contact regulations (such as EU 10/2011 and FDA 21 CFR relevant provisions), with a total migration of ≤10 mg/dm². Surface tension ≥38 dyn, facilitating subsequent localized cold foil stamping or QR code inkjet printing.

1. Sports Nutrition Packaging:

Standard and bulk packs for fitness and sports nutrition brands. The bag height and bottom width are designed based on protein powder bulk density for easy shelf display and shelf management. It aligns with subscription-based recurring purchase models, facilitating automated warehousing and batch traceability, reducing empty space within cartons, and improving overall carton loading efficiency.

2. Club Retail:

Stand-Up Pouches Custom are suitable for front-desk retail and sample packaging in gyms, studios, and other similar venues. The bag clearly displays ingredients and nutrition facts, facilitating on-the-spot inquiries and conversions. The self-standing design provides excellent display space on confined countertops. Combined with small-batch customization and multi-flavor parallel display, it supports rapid SKU updates and promotional labeling in stores.

3. Cross-Border E-commerce:

For cross-border direct mail or overseas warehouse fulfillment, the bag and outer carton are designed collaboratively to optimize volume-to-weight ratio and reduce logistics costs. The bag can be pre-printed with multilingual compliance information and batch number inkjet printing to meet labeling regulations in different markets, reducing manual relabeling and the risk of mislabeling, and improving fulfillment accuracy.

4. Trial and Combo Packs:

Stand-Up Pouches Custom are used for trial packs, flavor combo packs, or promotional mixed packs. Their small weight and differentiated layout allow for quick product testing of new products. The uniform, self-standing size facilitates display on endcaps and within gift boxes, with smooth openings and clear information differentiation, helping users select flavors and guide them towards repeat purchases, thus improving conversion rates and retention.
