55g Heavy Duty Cellophane for Industrial Tapes and Multiwall Bag Liners

Designed for demanding industrial applications, this 55 g/m² cellophane (custom heavy grade, interpolated from 45g and 60g) offers exceptional tensile strength (MD ≥70 N/15mm) and puncture resistance. It serves as a biodegradable base film for pressure‑sensitive adhesive tapes, tear tapes for e‑commerce cartons, and inner liners for multiwall paper bags. The film is oil‑resistant, anti‑static, and can be printed with brand markings. Despite its robustness, it remains fully compostable within 3‑6 months.

Process Introduction

This heavy grade is produced using the traditional viscose process with extended xanthation and controlled stretching during regeneration. The viscose (cellulose concentration 8‑9%) is extruded through a wider die gap and stretched less in the longitudinal direction to achieve greater thickness and cross‑direction strength. After coagulation in 10‑15% sulfuric acid, the film undergoes multi‑stage washing, desulfurization, bleaching, and plasticization with glycerol. Drying at 80‑120°C is followed by humidity conditioning (6‑8% moisture). The finished film can be coated with acrylic or rubber‑based adhesives for tape applications. No plasticizers or harmful solvents are used – the product is fully biodegradable.

Applications & Advantages by Category

• Adhesive Tapes – Base film for packaging tape, masking tape, and double‑sided tape; excellent adhesion and tear resistance.

• Tear Tapes – Reinforced strip for easy‑open cartons; high MD strength prevents premature breakage.

• Multiwall Bag Liners – Inner liner for cement, fertilizer, or pet food bags; moisture and oil barrier.

• Industrial Insulation – Dielectric film for cable wrapping and motor insulation.

• Heavy‑Duty Shipping Sacks – Protective wrap for machinery parts; puncture‑resistant and compostable.

Why Choose This Paper – 55g heavy cellophane replaces non‑biodegradable PET and BOPP films in industrial applications, offering comparable strength with full environmental compliance.
