Custom Resealable Pouches are a high-performance flexible packaging solution designed to meet modern packaging needs. The core of this packaging lies in its integrated resealable closure at the top, typically a zipper structure made of materials such as polyethylene, allowing users to maintain the packaging's seal after multiple uses, effectively extending product shelf life and enhancing convenience. The pouch body utilizes multi-layer composite material technology, with common structural combinations including polyester and polyethylene composites, or incorporating barrier layers such as nylon or metallized film.  High-quality, durable graphics and information are achieved through gravure or digital printing processes. This type of packaging is specifically developed for products requiring high protection, convenient storage, and brand differentiation. It is particularly suitable for materials sensitive to oxygen and moisture. Its customizable nature allows brands to develop bespoke solutions in terms of material structure, size specifications, and visual design, achieving an optimal balance of functionality, shelf appeal, and brand value.

1. Excellent Oxygen Barrier Performance

Utilizing multi-layer composite structures such as PET/NY/PE, the nylon layer significantly blocks oxygen penetration. Specifically, the oxygen transmission rate of this structure can be as low as 1.5 cm³/m²·24h·atm, effectively delaying rancidity and nutrient loss caused by oxidation, ensuring product stability during its shelf life.

2. Efficient Moisture Protection

The polyethylene inner layer, in conjunction with the overall structure, provides excellent water vapor barrier properties. Its water vapor transmission rate can typically be controlled within 2.0 g/m²·24h, indicating that the packaging effectively isolates environmental moisture, preventing the contents from clumping or deteriorating due to dampness.

3. Superior Sealing Reliability

The combination of the bag's heat seal strength and the mechanical properties of the customized PE zipper ensures secure initial and repeated sealing. Tests show that the heat seal strength of the bag edges can reach over 35 N/15mm, and after 50 cycles of opening and closing, the zipper's sealing peel strength still maintains over 85% of its initial value.

4. High Puncture Resistance

The incorporation of materials such as nylon or biaxially oriented polyester significantly enhances the packaging's puncture and tear resistance. For example, composite materials containing a nylon layer can have a puncture strength exceeding 12 N, effectively preventing packaging damage caused by external forces during transportation or storage.

5. Customized Printing Quality

Supports gravure printing, achieving exquisite printing effects with up to 10 colors, high color saturation, and strong adhesion. The printing resolution is fine, with line accuracy up to 175 lines/inch, and it also possesses excellent abrasion resistance; the ink detachment rate after abrasion testing is less than 5%, ensuring the lasting clarity of the brand image.

1. Dry Pet Food Packaging

Widely used for cat food, dog food, and other pet food products. Its high barrier properties extend shelf life to over 18 months, while the resealable design allows for convenient daily use and reduces waste caused by improper storage after opening, meeting pet owners' core needs for freshness and convenience.

2. High-End Snack Food Packaging

Suitable for easily perishable foods such as potato chips, nuts, and jerky. The packaging's low oxygen permeability and moisture barrier properties precisely control the internal environment, and the stand-up pouch design enhances shelf display, effectively maintaining the crispness and flavor of snacks for up to a year.

3. Coffee Bean and Powder Packaging

Designed for high-value, easily perishable products such as coffee beans, milk powder, and protein powder. The packaging's oxygen and moisture barrier functions significantly slow down the loss of coffee flavor or powder clumping.  Combined with a one-way degassing valve design to release carbon dioxide emitted by coffee beans, it is the preferred solution for professional product preservation.

4. Household Chemical Packaging

Suitable for products such as laundry detergent and cleaning agents. The excellent chemical stability of the inner layer of the material can withstand various chemical components, and its puncture resistance prevents damage during transportation. The resealable function allows for controlled dispensing and keeps the contents dry, improving safety and convenience of use.

5. Electronic Component Moisture-Proof Storage

Used for the transportation packaging of small electronic components and circuit boards. The packaging's extremely low water vapor transmission rate ensures a dry internal environment during logistics, effectively preventing oxidation and damage to precision components due to moisture, making it a critical protective packaging in the electronics industry supply chain.
