The custom-made moisture-proof three-side seal seafood packaging bag is a high-performance packaging material specifically designed for seafood products. It uses food-grade composite materials and features a three-side seal structure for stable sealing, offering excellent moisture resistance, oxidation resistance, and odor barrier properties. Whether for frozen seafood, fresh seafood, cured seafood, or ready-to-eat seafood products, this packaging bag provides reliable protection.
The core value of the product is reflected in the following aspects:
Maintaining the original freshness and flavor of seafood; extending shelf life and reducing spoilage; improving transportation and storage safety; enhancing product display; and meeting food hygiene and safety standards.
To meet the high standards of seafood packaging, the packaging bags typically use PA/PE, PET/PE, or EVOH multi-layer composite structures. These materials not only possess food-grade safety but also have excellent physical and chemical properties.
Seafood is highly susceptible to absorbing moisture from the air during storage, leading to deterioration in taste or bacterial growth. High-barrier materials effectively block moisture, keeping the seafood dry and clean.
The transparent material allows consumers to visually observe the color and quality of the seafood, especially suitable for supermarkets and e-commerce sales.
Sharp parts such as shrimp shells, crab claws, and shellfish can easily puncture ordinary packaging bags, while the multi-layer composite structure has higher toughness, effectively preventing bag breakage and leakage.
The materials comply with food contact standards and do not release harmful substances, ensuring that the seafood remains uncontaminated during storage.
The three-side seal structure is one of the most stable and commonly used sealing methods in food packaging. Its advantages include: strong sealing, not easy to crack; suitable for vacuum packaging, improving preservation effect; flat bag shape, convenient for stacking and transportation; customizable size, thickness, and printing according to needs; for seafood products, the three-side seal structure effectively prevents liquid leakage, maintaining clean and hygienic packaging. IV. Core Functions: Comprehensive Performance in Durability, Hygiene, and Freshness Preservation
Seafood typically needs to be transported in low-temperature or even frozen environments. The packaging bags remain flexible at low temperatures and will not become brittle or deform.
The sealed packaging isolates external air, dust, and bacteria, ensuring that seafood remains hygienic during transportation and storage.
High-barrier materials reduce oxygen ingress, slowing down the oxidation and discoloration of seafood and maintaining the freshness of the meat.
Seafood has a strong odor, and the odor-blocking function of the packaging bag prevents odor leakage, improving the quality of the storage environment.
Used for packaging frozen shrimp, fish fillets, shellfish, crabs, and other products, suitable for vacuum packaging and frozen storage.
The low-temperature resistance and pressure resistance of the packaging bags ensure that seafood remains intact during long-distance transportation.
Transparent packaging enhances display effects and facilitates consumer selection.
Suitable for fresh seafood delivery, preventing leakage and damage, and improving user experience.
Used for packaging ready-to-eat seafood, marinated seafood, and semi-finished meal kits.
Customized moisture-proof three-side seal seafood packaging bags, with their durability, hygiene, freshness preservation, and customizability, have become the preferred packaging solution for the seafood industry. It not only improves food safety and quality but also brings higher transportation efficiency and brand value to businesses. Whether in processing, transportation, storage, or sales, this packaging bag provides stable and reliable protection and is an indispensable part of the modern seafood supply chain.
The quality of seafood changes very quickly, especially at room temperature, where bacterial growth accelerates exponentially, leading to rapid spoilage. Even in refrigerated or frozen environments, improper packaging can lead to problems such as freezer burn, dehydration, discoloration, and flavor transfer. Therefore, packaging bags play a crucial role in maintaining the quality of seafood.
When seafood is exposed to air, oxygen accelerates oxidation, causing discoloration and a decline in flavor. The barrier layer in the packaging bag effectively reduces oxygen penetration, slowing down the oxidation rate and maintaining the natural color and texture of the seafood.
Seafood is highly susceptible to moisture absorption during storage, leading to softening of the surface and bacterial growth. Moisture-proof materials can block moisture from the air, keeping the seafood dry and extending its shelf life.
Seafood has a strong odor, and if the packaging is not sealed properly, it can easily contaminate other foods or the storage environment. High-barrier packaging bags effectively lock in odors, maintaining a clean environment and preventing the seafood from absorbing external odors.
In a frozen environment, the surface of seafood is prone to freezer burn due to water evaporation, affecting taste and appearance. The barrier layer of the packaging bag reduces moisture loss, maintaining the freshness of the seafood.
With the diversified development of the food industry, companies' packaging needs are becoming increasingly personalized. Customized moisture-proof three-side sealed seafood packaging bags can be flexibly customized according to different products, sales channels, and brand positioning.
Different seafood products have different sizes and shapes. For example, shrimp and lobster require longer bags; shellfish and fish fillets require wider bags; ready-to-eat seafood requires bags suitable for vacuum packaging. Customizable sizes ensure that the packaging fits the product, improving aesthetics and practicality.
Depending on the transportation method, storage environment, and product characteristics, different material thicknesses can be selected:
Frozen transportation: Thicker material recommended
Ready-to-eat seafood: Medium thickness can be selected
E-commerce shipping: Higher compression resistance required
The packaging bag can be printed with brand logos, product information, nutritional facts, and usage instructions to enhance brand image. 4. Customizable Materials
Based on product requirements, you can choose from:
High-transparency materials; high-barrier materials; high-temperature resistant materials; vacuum-sealable materials; customized designs make the packaging bags better suited to the company's product positioning and market needs.
Seafood products have diversified sales channels, and the packaging requirements vary across different channels. Customized moisture-proof three-side sealed seafood packaging bags can adapt to various sales scenarios.
In supermarkets, transparent packaging bags can enhance product display and allow consumers to intuitively judge the quality of seafood. The three-side sealed structure makes the bag flat and easy to display.
E-commerce seafood delivery has higher packaging requirements:
Must be leak-proof; must be pressure-resistant; must be low-temperature resistant; must maintain a clean appearance; this product can meet these requirements, reducing damage rates and improving user experience.
During cold chain transportation, temperature changes are frequent, and the packaging bag must have:
Freeze-crack resistance; pressure resistance; moisture resistance; the multi-layer composite structure ensures that the seafood remains stable during transportation.
Catering companies often use semi-finished or ready-to-eat seafood, and the packaging bags need to be:
Vacuum-sealable; heat-sealable; high-temperature sterilization resistant; this product can meet these processing requirements and improve food safety.
As consumers' attention to food safety and quality continues to increase, seafood packaging will develop towards higher standards:
Higher barrier performance; more environmentally friendly materials; more intelligent packaging design; stronger brand display capabilities; customized moisture-proof three-side sealed seafood packaging bags will continue to play an important role in the industry, providing safer, more efficient, and more professional packaging solutions for the seafood supply chain.
