Twisted-Handle, Flat-Handle, and Die-Cut Handle: Analyzing the Process Differences and Innovations in Nanwang’s Paper Bag Production

In today’s packaging industry, paper bags are more than carriers of goods—they are also essential tools for delivering brand values and supporting eco-friendly practices. As a leading manufacturer of sustainable packaging, Nanwang leverages advanced processes and technical expertise to produce paper bag solutions with different handle styles. This article explores the production distinctions between twisted-handle, flat-handlee die-cut handle paper bags, while highlighting Nanwang’s innovations and professional capabilities.

1. Sacos de papel com alça torcida: A Blend of Strength and Classic Craftsmanship

Twisted-handle paper bags are widely used in high-end retail and gift packaging. Their handles, made of twisted paper rope or cotton rope, provide excellent load-bearing strength and a comfortable grip.

Material Selection and Preprocessing

Nanwang selects high-quality, eco-friendly kraft paper, recycled paper, or coated paper as the main body material. For handles, twisted paper rope or core-spun cotton rope is commonly used to ensure both durability and visual appeal. All printing is carried out with non-toxic water-based inks, achieving a balance between color performance and environmental safety.

Perforation and Assembly Process

With high-precision molds, Nanwang perforates and positions the bag body for handle attachment. Automated equipment then threads the handles, ensuring strong adhesion and uniform quality while boosting production efficiency.

Sustainability Practices

Biodegradable adhesives and FSC-certified papers are integrated into production, aligning with international sustainability standards and meeting the environmental demands of global brands.

2. Sacos de papel de pega plana: Integrating Unified Design and Efficient Production

Flat-handle paper bags are valued for their simple structure, ease of stacking, and practical use in shopping or lightweight packaging. Their design merges both functionality and aesthetics.

Automated Forming Process

Bag bodies and handles are die-cut and creased from the same paper sheet, then folded, glued, and formed using high-speed machinery. Nanwang’s automated equipment ensures consistency while significantly enhancing production capacity.

Structural Reinforcement and Load-Bearing Optimization

Multi-layer composites or reinforced handle connections strengthen the structure, ensuring stability even under medium loads.

Customization and Brand Applications

Nanwang offers customization with various paper types—pure pulp, lined, or recycled—and advanced printing effects. For example, brands choosing flat handle paper bags can align packaging design with their brand image while meeting functionality needs.

3. Sacos de papel com alça cortada: Minimalist Design and Resource Efficiency

Die-cut handle paper bags are created by cutting handle openings directly into the bag body. This streamlined approach eliminates additional materials and highlights a minimalist design—ideal for brands emphasizing sustainability and aesthetics.

High-Precision Die-Cutting Technology

Nanwang uses advanced die-cutting machines to complete contour cutting in a single stamping process, producing smooth, burr-free edges that ensure safety and comfort in use.

Material Strength and Structural Design

Strong kraft paper or recycled white cardstock is selected for its tensile toughness. Local creasing and reinforcement ensure durability while simplifying manufacturing.

Environmental and Economic Benefits

The elimination of extra handle materials and assembly reduces raw material use and carbon emissions, supporting circular economy principles. Through this process, Nanwang helps clients achieve lightweight, low-carbon packaging.
