Material Layer Breakdown:
Outer Layer: Typically uses PET (Polyethylene Terephthalate) or BOPP (Biaxially Oriented Polypropylene) to provide excellent printability and mechanical strength. The outer layer material is scratch-resistant and abrasion-resistant, effectively protecting the printed pattern and ensuring the packaging's aesthetic appeal during distribution.
Barrier Layer: Uses pure aluminum foil (AL), the thickness of which can be adjusted according to barrier requirements. The aluminum foil layer provides near-absolute protection against oxygen, water vapor, ultraviolet light, and visible light, fundamentally preventing food spoilage due to oxidation, deliquescence, and light exposure.
Reinforcing Layer (Optional): Some high-end packaging adds a nylon (PA) layer, forming a PET/AL/PA/PE structure. The nylon layer gives the packaging excellent puncture resistance and physical toughness, making it particularly suitable for packaging pet treats with sharp bones or hard particles.
Inner Layer: Typically made of PE (polyethylene) or CPP (cast polypropylene), these are heat-sealable materials that form a strong seal upon heating, directly contacting food to ensure food safety.
Inert Gas Preservation: Before sealing, advanced vacuum technology removes air from the packaging bag, effectively reducing oxygen content. Then, high-purity food-grade nitrogen (N2) or other inert gases are introduced. Nitrogen effectively replaces residual oxygen, inhibits the growth of aerobic microorganisms, and slows down the oxidative rancidity of oils, thus maximizing the freshness, taste, and nutritional value of pet food.
Precision Heat Sealing Process: High-precision heat sealing equipment is used to precisely control the temperature, pressure, and time of the composite film, ensuring a smooth, strong seal with extremely high airtightness. Even under pressure or during transportation, gas leakage is effectively prevented, ensuring the inert gas environment inside the packaging remains intact.
Eight-Side Seal Stand-Up Pouch: The bottom and eight folded edges seal the pouch, ensuring stability during display and creating a sophisticated, high-end visual effect. Large capacity and ample printing area make it ideal for brand promotion.
Four-Side Seal Pouch: Four-side seal provides a full, three-dimensional shape and strong load-bearing capacity, making it particularly suitable for large-capacity pet dry food packaging.
Back-Seal Pouch: Back-sealed design offers a simple structure and relatively low cost, suitable for small to medium-sized pet snacks.
Zipper Stand-Up Pouch: Adds a zipper or self-sealing strip to the stand-up pouch design. Consumers can easily reseal it after opening to prevent moisture damage, allowing for multiple uses and greatly improving convenience.
Unique Shaped Bags: Custom-made bags in special shapes, such as bone or fish shapes, can be created to increase product appeal and brand recognition. 2. User-Friendly Design
Easy-Tear Cutout: Easy-tear cutouts are provided on the packaging edges, allowing consumers to easily open the packaging without scissors, preventing leakage due to improper tearing.
High-Definition Printing: Utilizing advanced 10-color gravure printing technology, high-precision color patterns and text printing are achieved, with rich colors and clear layers, vividly showcasing product selling points and attracting consumer attention.
Matte/Gloss Surface Treatment: Matte or glossy surface treatments can be selected according to brand image. Matte effects convey a more upscale and understated look; glossy effects are more vibrant and lively.
Anti-Counterfeiting Traceability System: Can integrate QR codes or variable data printing, enabling product traceability and anti-counterfeiting verification, enhancing consumer trust in the brand.
Plate Making: High-precision printing rollers are made according to customer designs.
Printing: Environmentally friendly, benzene-free, and ketone-free inks are used for high-speed printing to ensure print quality.
Lamination: Multiple layers of materials are bonded together using dry lamination or solvent-free lamination techniques to ensure composite strength and barrier properties.
Curing: The laminated film rolls are placed in a curing chamber where the adhesive is fully cured under controlled time, temperature, and humidity, eliminating residual solvents and ensuring safe and non-toxic packaging.
Slitting and Bag Making: The cured film rolls are slit to the required width and automatically made into bags, ensuring precise dimensions.
Quality Inspection: Finished bags undergo rigorous quality inspection, including appearance, dimensions, seal strength, and barrier performance.
Barrier Performance Testing: Oxygen permeability testers and water vapor permeability testers are used to sample and test products to ensure the packaging's barrier performance meets design standards.
Sealing Performance Testing: A negative pressure sealing tester is used to simulate pressure changes during high altitudes or transportation to test the reliability of the seal.
Burst Pressure Testing: A burst pressure tester is used to evaluate the pressure resistance of the packaging bags, preventing damage due to compression during transportation and handling.
Residual Solvent Testing: Regular testing of inks and adhesives used in the production process ensures packaging meets food-grade safety standards.
Personalized Design: Customized packaging design solutions are provided based on brand positioning, product characteristics, and target audience, comprehensively meeting customer needs from bag type and materials to printing effects.
Professional Consultation: Professional packaging technology consultation is provided to assist customers in selecting the most suitable packaging solutions for their products and budgets.
Dry Food: Fresh-keeping packaging for various pet dry foods such as dog food and cat food.
Snacks: High-quality pet snacks such as jerky, chew sticks, and freeze-dried snacks.
Wet Food: A combination of aluminum foil trays and lid films, suitable for canned wet food requiring sterilization.
Prescription Food: Special pet foods with extremely high freshness requirements.
Export Products: Meeting the stringent standards of the international market for packaging materials and preservation technologies.
