Custom food pouches are a form of sealed packaging made primarily of multi-layered composite plastic film using heat-sealing technology. They can be customized according to the type of food, shelf life, and transportation method, including parameters such as size, thickness, printing content, and opening method. This type of packaging is typically composed of PET, PE, PA, CPP, or aluminum foil composite film, with a thickness ranging from 60 to 150 microns, meeting requirements for moisture and oxidation prevention while extending shelf life. Custom food pouches are widely applicable to vacuum sealing, gas-flushing preservation, and ambient temperature storage systems, making them an indispensable packaging solution in the modern food industry. Their production emphasizes barrier properties, sealing, and printing precision, balancing brand display and food safety requirements, and making them suitable for automated filling and high-efficiency production lines.

1. Excellent Temperature Resistance:

The bag material maintains stable performance within a temperature range of -20℃ to 120℃, without becoming brittle or deformed, making it suitable for frozen foods, hot-filled products, and retortable products. The high-temperature sealing layer uses CPP or RCPP material, tested by SGS and FDA, and does not release harmful substances, meeting GB 9685 and EU 10/2011 safety standards. Even when used in continuous high-temperature sterilization environments, it maintains excellent sealing and transparency. This performance makes it an ideal choice for packaging heat-processed foods.

2. Superior Sealing Performance:

Custom Food Pouches use high-strength sealing material with a heat-sealing temperature range of 120℃ to 180℃, with a heat-sealing strength ≥40N/15mm. The three-side seal structure is integrally formed through high-pressure heat sealing, ensuring uniform sealing at the bag opening, pressure resistance, and no delamination. Drop tests and vacuum leak tests have verified that the product's airtightness meets the industry's Class A standard (≤0.1% gas leakage rate). This sealing performance not only prevents leakage and oxidation but is also suitable for vacuum gas-filled sealing and automated production lines, reducing packaging loss rates.

3. High Printing Precision:

Utilizing a high-speed gravure printing press for multi-color printing, with a resolution of up to 150 lines per inch, it achieves perfect reproduction of fine lines and gradient patterns. Supporting up to 10 colors, all inks are FDA and EU food-grade material certified, with a rubbing fastness ≥ Grade 4. Glossy or matte finishes are available to enhance the packaging's sophistication and brand recognition. Zhongxing employs a precision tension control system during the printing process to ensure roll-to-roll registration errors are less than ±0.15mm, presenting a more professional visual quality.

4. High Barrier Properties:

Custom Food Pouches utilize a multi-layered composite structure such as PET/AL/PE or PA/CPP, providing excellent gas and water vapor barrier properties. Oxygen permeability is less than 1.0 cm³/m²·24h, and water vapor permeability does not exceed 0.8 g/m²·24h, effectively preventing the impact of air, light, and odors on food. The bag's barrier layer thickness is precisely controlled within ±2 micrometers, ensuring stable protection even in high humidity environments. Whether it's coffee powder, nuts, or dehydrated vegetables, they can maintain their original flavor and aroma for a long time.

5. Sustainable and Environmentally Friendly:

With the upgrading of global environmental regulations, Zhongxing offers a variety of environmentally friendly solutions, including all-PE or all-PP single-structure films that are recyclable. Production utilizes solvent recovery systems, low-VOC inks, and energy-saving drying technology, reducing carbon emissions by more than 25%. Materials are RoHS and REACH compliant, meeting EU green packaging requirements, helping customers comply with ESG and sustainable development standards, and providing strong support for building an environmentally friendly brand image.

1. Snacks and Confectionery:

Three-Side Seal Custom Food Pouches maintain the crisp texture and aroma of nuts, biscuits, dried fruits, and other food products. The inner moisture-proof film effectively blocks moisture, while the outer high-strength PET provides puncture resistance. Their lightweight and easily stackable nature reduces storage costs, and they support European-style hanging holes and easy-tear designs for convenient display and consumer opening, making them widely used by snack food brands.

2. Frozen and Ready-to-Eat Foods:

Custom Food Pouches are suitable for frozen dumplings, meat, seafood, and other products. The material can withstand freezing temperatures down to -30°C without cracking. The high heat-sealing strength of the pouches ensures they remain sealed during quick-freezing and transportation, preventing ice crystals and odor penetration. Some products can be treated with an anti-slip surface to improve the gripping efficiency of automated packaging lines. They maintain flexibility after cold-impact testing, making them an ideal solution for cold chain packaging.

3. Condiments and Sauces:

Suitable for packaging fluids such as ketchup, hot sauce, and hot pot base. Utilizes high-barrier materials to prevent oil penetration and odor diffusion. The bag features uniform heat sealing, supports high-temperature filling (up to 100℃), and possesses excellent oil resistance. Strong sealing and structural stability prevent leakage during transportation and display. Vivid surface printing enhances product visibility and brand image on the shelf.

4. Coffee and Tea Packaging:

Custom Food Pouches are designed for premium coffee beans, ground coffee, and tea products. The bag uses an aluminum foil composite structure to effectively block light and oxygen, maintaining aroma concentration. A customizable one-way vent valve releases carbon dioxide, preventing internal bulging. The printed surface can combine matte and spot UV effects to highlight brand quality. Passes full-seal and odor-barrier tests to ensure product freshness and safety during long-distance transportation.
