Custom Printed Stand Up Resealable Bags are a high-performance flexible packaging solution that combines product protection, brand presentation, and user convenience. Their unique flat-bottom design allows the bags to stand upright after filling, facilitating shelf display and easy access. The resealable feature, thanks to a precisely engineered, proprietary self-sealing zipper structure, allows users to open and close the bag multiple times, ensuring the contents remain in optimal condition throughout their usage. These bags utilize a multi-layer composite material structure and support various printing processes, effectively protecting against external environmental factors and becoming a mobile brand billboard through high-quality custom printing. They are widely used in various industries, including food and consumer goods, where maintaining product freshness and convenience is essential.

1. Multi-Layer Composite Material Structure

The packaging utilizes a multi-layer composite material structure, such as a PET/NY/PE combination, which effectively blocks oxygen and moisture penetration. Its aluminum foil lining or metallized layer provides a high level of light and gas barrier properties, with an oxygen transmission rate of less than 1.0 cm³/m²·day·atm and a water vapor transmission rate of less than 1.0 g/m²·day, ensuring the contents are protected from moisture and oxidation, maintaining their original quality for a long time.

2. Secure Self-Sealing Design

The bag opening features a high-density polyethylene self-sealing zipper, manufactured using a precision compression process. This zipper boasts excellent repeated opening and closing performance; laboratory tests show it can withstand over 200 repeated opening and closing cycles without losing its sealing ability, and the peel strength after closing reaches over 4.5 N/15mm, ensuring a tight and reliable seal every time.

3. Stable Self-Standing Structure

The bag bottom features a reinforced flat bottom design, forming a stable base through special film pressing and heat sealing technology. After filling, the bag can stand upright on shelves or tables without easily tipping over. Its bottom load-bearing capacity has been tested to stably support up to 2 kilograms of contents, significantly improving display effect and ease of use.

4. High-Definition Brand Printing

Supports both gravure and digital printing methods. Gravure printing achieves a fineness of up to 175 lines/inch, with high color saturation, suitable for large-scale production; digital printing offers flexibility for small-batch customization, supporting complex patterns and gradient colors, with a wide color gamut coverage, accurately reproducing brand logos and design details, enhancing product added value.

5. Customized Production Support

Provides comprehensive OEM and ODM services. From bag material, size specifications, zipper type to bottom shape, everything can be customized according to customer specific needs. The production process is highly flexible, able to quickly respond to different order volumes, from sample production to large-scale production and delivery, ensuring that the packaging solution perfectly matches the product characteristics.

1. Snack Food Packaging

Widely used for packaging dry or fried foods such as potato chips, nuts, and biscuits. Its excellent moisture and oxygen barrier properties can extend product shelf life by more than 30%. The stand-up pouch design enhances shelf appeal, while the resealable feature allows consumers to consume the product in portions, directly guaranteeing the crisp texture and fresh flavor after opening.

2. Coffee Bean and Powder Packaging

Specifically designed for products sensitive to aroma and humidity, such as coffee beans, milk powder, and protein powder. High-barrier materials effectively prevent aroma loss and block external moisture intrusion. Water vapor transmission rate (WVTR) is typically required to be below 2 g/m²·day. The stand-up pouch design facilitates pouring and storage, and the resealable feature reduces powder clumping.

3. Pet Food Packaging

Suitable for dry pet food and treats. The packaging needs to withstand the weight of the contents. The sturdy flat-bottom structure and durable resealable zipper ensure the packaging remains intact during distribution and allows pet owners to easily access the food multiple times daily, while maintaining the freshness and palatability of the pet food.

4. Household Chemical Packaging

Used for daily chemical products such as laundry detergent, bath salts, and soap granules. The packaging material has good resistance to the contents, preventing the leakage of chemical properties. The resealable design effectively controls usage and keeps the product dry, while the stand-up display feature maximizes brand information and product selling points in a retail environment.

5. High-End Health Supplement Packaging

Serving health products such as vitamins and herbal extracts. High-standard light and oxygen barrier properties are core requirements, protecting light and oxygen-sensitive nutrients from degradation and loss of efficacy. Exquisite custom printing helps to create a professional and trustworthy brand image, while the convenient resealable feature enhances the user experience and perceived value of the product.
