Color-printed, PE-lined, laminated packaging bags for feed additives | High barrier, moisture-proof | Specifically for 25 kg bags of vitamins and premixes

Product Overview:
This product is a color-printed and laminated feed additive packaging bag with a PE inner liner, specifically designed for high-value feed additives such as 25kg vitamins and premixes. The outer layer is made of PP (polypropylene) woven fabric with a color-printed laminated surface, providing vibrant patterns and wear resistance. The inner layer is compounded with a high-barrier PE inner liner film, effectively blocking moisture and oxygen permeation. The bag is available in flat or valve bag styles, with a heat-sealed bottom, offering excellent high-barrier moisture resistance, leak prevention, and high load-bearing capacity. Custom printing is supported, and the bag complies with relevant regulatory requirements for feed additive packaging.

Applicable Materials:
Vitamin premixes, mineral premixes, medicinal additives, enzymes, amino acids, probiotics, mold inhibitors, antioxidants, and other highly active feed additives.

Core Advantages:
High-barrier moisture resistance, PE inner liner for oxygen and moisture barrier, color-printed lamination for brand display, 25kg standard specification, heat-sealed bottom for leak prevention, suitable for vitamins/premixes, and compliant with feed additive packaging regulations.

Material & Process:

Outer Layer: PP (polypropylene) woven fabric

Lamination Layer: Color PE film lamination (waterproof, dustproof, gloss-enhancing, print-protecting)

Inner Layer: High-barrier PE inner liner film (moisture-proof, oxygen-barrier)

Structure: PP woven fabric + color-printed lamination layer + PE inner liner film (three-layer composite)

Bag Types: Flat bag / Gusseted bag / Square-bottom valve bag (optional)

Printing: 2 to 7-color gravure color printing and lamination, vibrant patterns, wear-resistant, non-fading

High-Barrier Moisture Resistance (Core):

PE Inner Liner Film: Built-in high-barrier PE film, water vapor transmission rate ≤2.5g/(m²·24h) (better than national standard)

Lamination Enhancement: Outer layer color-printed lamination provides dual moisture protection

Heat-Sealed Bottom: Bottom heat-sealed, no pinholes, excellent sealing

Effect: Effectively prevents vitamins and premixes from moisture absorption and oxidation, maintains active ingredient stability, shelf life up to 18 months or more

Oxygen Barrier Performance:

The PE inner liner film also offers oxygen barrier performance, with oxygen transmission rate ≤20cm³/(m²·24h·0.1MPa)

Effectively prevents vitamin oxidation and loss of enzyme activity

Leak Prevention Performance:

Heat-Sealed Bottom Process: Bottom completely sealed, no leakage risk

Integrated PE Liner: Inner bag and outer bag are compounded or co-extruded, no layered leakage

Drop Test: 25kg load, 1.2m free fall, no rupture or material leakage after six-sided drops

High Load-Bearing Capacity:

Tensile Strength: ≥700N/50mm (30% higher than national standard), capable of carrying 25kg

Puncture Resistance: Tight woven structure prevents additive particles from piercing the bag

Stacking Resistance: Can be stacked 8-10 layers high without deformation

Color-Printed Lamination Features:

Waterproof: Surface lamination layer effectively blocks liquid water penetration

Dustproof: Smooth surface resists dust adhesion, keeping the bag clean

Gloss Enhancement: Lamination makes printed colors more vibrant and bright

Wear Resistance: Lamination protects printed patterns from friction during storage and transportation

Brand Display: White or colored base makes brand logos and product information clear and eye-catching

Packaging Drop Test:
25kg load, 1.2m free fall, no rupture or leakage after six-sided drops

Corrosion Resistance Rating:
★★★★★ (Highly resistant to vitamins, minerals, and medicinal ingredients)
