Versatile Heat Sealable Paper for Food and Consumer Packaging
Custom heat seal paper is a specialized packaging substrate that combines the print quality and tactile properties of paper with the hermetic sealing capability of heat-sealable coatings. When passed through a heat sealer or formed into bags, pouches, sachets, or wraps, heat seal paper creates a strong, food-safe seal that protects contents from moisture, contamination, and tampering. It is a widely used material in food service, bakery, deli, specialty food retail, pharmaceutical, and personal care packaging applications. Teal Packaging works with manufacturing partners to produce custom heat seal paper with a minimum order of 50 units, free shipping to the US, Canada, UK, and Australia, and a two-week standard turnaround.
Unlike plastic-only flexible packaging, custom heat seal paper brings the consumer appeal of natural paper aesthetics to applications that require a functional seal. Kraft-finish and white heat seal papers in particular resonate with consumers who associate paper packaging with environmental responsibility and product freshness, making them popular choices for artisan food brands, organic food producers, and specialty retail formats. The combination of custom print and heat sealable performance makes this substrate suitable for a wide range of packaging applications.
From coffee and tea portion sachets to baked goods wrap, deli counter paper, single-serve food packs, and pharmaceutical sachet packaging, custom heat seal paper covers a broad range of applications within a single material family. Teal Packaging's free design support team helps brands identify the right heat seal paper specification for their product and develop print designs that maximize impact on the formatted surface.
Materials and GSM Specifications for Heat Seal Paper
Heat seal paper is available in multiple base substrates and coating weights, each suited to specific application requirements. Teal Packaging offers the following specifications for custom heat seal paper:
- Kraft heat seal paper (40-90 gsm base weight): Unbleached kraft paper with a heat-sealable polyethylene coating on one or both sides. Provides strong seal integrity with a natural brown paper aesthetic favored by artisan food and organic product brands. Available in wet-strength grades for high-moisture applications such as deli and bakery wrapping.
- White heat seal paper (40-80 gsm base weight): Bleached white paper with PE heat seal coating. Provides a clean, bright print surface with excellent ink adhesion, suitable for high-detail brand graphics and regulatory label panels on sachet and wrap applications.
- Greaseproof heat seal paper (35-60 gsm base weight): Combines grease-resistant paper properties with a heat-sealable coating layer, making it ideal for fatty or oily food products. Commonly used for burger wrappers, cheese paper, deli meat wrapping, and specialty bakery applications.
- MG (machine-glazed) heat seal paper (40-80 gsm): One-side-glazed paper with a smooth, non-porous surface on the glazed side and a natural texture on the reverse, with heat seal coating applied to the intended seal face. Provides good moisture resistance and a distinctive print surface.
All paper substrates are FSC-certified. Soy-based inks are used for all printed heat seal paper production. Food-contact compliance is maintained across all coating systems used in heat seal paper manufacturing.
Customization Options for Heat Seal Paper
Teal Packaging's free design support team configures your custom heat seal paper specification to match your application, product, and brand requirements:
- Format options: Roll stock for in-line sealing equipment, pre-cut sheets for manual wrap applications, pre-formed pouches and sachets sealed on three sides, flat-bottom bags, pillow sachets, and fin-seal wrap roll formats.
- Print options: Flexographic printing up to eight colors on roll stock, digital printing for shorter runs and variable data requirements, full CMYK process color, and Pantone spot color matching for brand consistency.
- Surface treatments: Matte or gloss finish coatings over the print layer for enhanced visual quality and surface protection during handling and shelf display.
- Functional specifications: One-side or two-side heat seal coating, specified seal temperature and dwell time, tear strip integration, and perforated tear-open features for sachet and pouch applications.
- Custom dimensions: Roll width, sheet dimensions, and pre-formed pouch sizes are produced to your exact specification for compatibility with your sealing equipment or hand-seal process.
For brands using heat seal paper as part of a broader packaging program, Teal Packaging can coordinate with complementary rigid packaging. Explore custom kraft boxes for secondary packaging around heat-sealed products, or custom food boxes for outer retail packaging that presents heat-sealed pouches and sachets in a branded carton format.
Standard Sizes for Custom Heat Seal Paper (Inches)
Teal Packaging produces bespoke heat seal paper in standard and fully custom dimensions across all formats:
- Sachet format (single-serve, portion packs): 3 x 4 inches to 5 x 7 inches finished sachet size
- Wrap sheet format (deli, bakery, food service): 10 x 10 inches to 18 x 24 inches per sheet
- Roll stock (for inline sealing equipment): Roll widths from 4 inches to 24 inches, length to specification
- Pillow pouch format: 3 x 5 inches to 8 x 12 inches finished pouch size
- Three-side seal pouch: 4 x 6 inches to 10 x 14 inches finished pouch size
Custom dimensions are available for all formats. Provide your target product weight, fill dimensions, and sealing equipment specifications when requesting a quote and the team will confirm appropriate paper dimensions and coating weight for your application.
Sustainability in Heat Seal Paper Packaging
Paper-based flexible packaging, including made-to-order heat seal paper, generally carries a more favorable environmental profile than equivalent plastic flexible packaging formats, particularly where paper content is high relative to coating weight. Teal Packaging uses FSC-certified paper across all heat seal paper substrates, ensuring responsible forest management throughout the supply chain. Soy-based inks are used for all print layers, reducing VOC emissions during the print process.
For brands targeting compostable or industrially biodegradable packaging, heat seal paper with PLA (polylactic acid) biopolymer coatings is available as an alternative to polyethylene coatings, providing heat seal functionality with improved end-of-life compostability. These specifications are appropriate for food service, bakery, and short shelf life food product applications where the compostable claim supports brand positioning.
Pairing heat seal paper with FSC-certified secondary packaging from Teal Packaging creates a fully traceable, sustainably sourced packaging supply chain. Explore custom mailer boxes for e-commerce shipment of heat-sealed food and specialty products, or custom corrugated boxes for retail-to-warehouse outer packaging programs.
