Block Header Plastic Bags Manufacturers, Suppliers, Factory

1. Brief Introduction

(1) Product Description

Block header bags are supplied in pre-separated pads or blocks mounted on a dispenser through a punched header and pulled one bag at a time along a perforation for fast single-hand access
Available in HDPE LDPE and LLDPE resins with custom sizing printing and private labeling to match different product weights and packaging needs
Designed for high-volume dispensing in produce, food-service, hygiene, and light-industrial operations — pre-indexed for faster reloading and more reliable one-at-a-time dispensing than roll-fed or loose flat bags.

(2) Applicable Scenarios & Target Audience

Channel Type	Applicable Scenario	Target Audience
Retail Produce	Produce dispensing at supermarket stands for high-turnover restocking	Supermarkets and grocery retailers
Food Service	Bakery deli and food prep counters for wrapping and bagging items to order	Food service and hospitality operators
Healthcare and Hygiene	Glove disposal specimen collection and general hygiene waste stations	Healthcare facilities and hygiene service providers
Light Industrial	Bagging small components at assembly and kitting stations	Manufacturers and parts distributors
Warehouse and Fulfillment	Bagging small SKUs at pick-and-pack stations during order fulfillment	Warehouse and fulfillment operators

(3) Bag Format & Dispensing

Bags stay pre-indexed and separate one at a time along a perforation with header width punch and hole spacing built to match the dispenser exactly for use at a counter or workstation

(4) Perforation Tear-off & Seal Strength

Perforation tear-off force and seal type are calibrated together so bags release cleanly without ripping or dropping multiple bags while seal strength stays matched to film gauge and product weight

(5) Quality Assurance & Customization

Every specification is checked against tolerance and confirmed with pre-production samples or a pilot batch on the buyer's dispenser before the full order is locked in writing

2. Basic Specifications

Block header bags for produce, food-service, and light-industrial use are typically sized between 10 and 20 inches, with block counts and carton quantities that scale from daily counter use up to institutional volume. The specifications below reflect current market ranges for size, film thickness, and packaging, and can be adjusted to match a buyer's dispenser and order volume.

Item	Specification	Remarks
Size (L x W)	10 x 13" (25.4 x 33cm) 12 x 18" (30.5 x 45.7cm) 14 x 20" (35.6 x 50.8cm)	Custom sizes available
Bags per Block	50 to 100 bags per block for produce and counter use 200 or more bags per block for institutional and industrial use	Portable box packs also available, priced per unit piece rather than per block
Header and Hole Pattern	Punched header width and hole spacing sized for standard counter and wall-mounted dispensers	Must match the buyer's dispenser exactly; confirm with a photo or sample before production
Film Color	Clear Frosted Colored	Custom colors and printing available
Thickness	Standard: 0.35-0.5 mil (9-12 microns) Heavy-duty: 0.7-1.2 mil (18-30 microns)	Thickness customizable; heavy-duty grade improves puncture and tear resistance for sharp or heavier items
Bags per Carton	300 pcs/box x 4 boxes/carton = 1,200 pcs/carton 150 pcs/box x 24 boxes/carton = 3,600 pcs/carton	Packaging quantity adjustable by size and thickness for calculating volumetric weight

3. Material & Safety

Resin selection is the main factor in how a block header bag performs under load, with HDPE, LDPE, and LLDPE each suited to different product weights and puncture risks. The table below outlines the raw material options, recycled content availability, and eco attributes that can be specified for this product.

Item	Specification	Remarks
Raw Material	HDPE for lightweight dry goods (primary direction) LDPE for puncture resistance on sharp items LLDPE for stretch on heavier or irregular loads	Resin choice should match the intended load; the wrong resin causes tearing that only shows up after a full order is in use
Recycled Content	Standard product uses virgin material Custom post-consumer recycled content (PCR) ratio available	If recycled content is required please confirm ratio and certification in advance
Eco Attribute	Recyclable Biodegradable option available on request	Biodegradable material is a custom order option; cost and lead time confirmed separately
Note: All are BPA-free, and relevant compliance documentation (FDA, LFGB, REACH, RoHS, etc.) can be provided based on the target market. Compostable material is also available on request.

4. Product Physical Properties

Physical performance for block header bags is verified through factory lab testing of tensile strength, elongation, impact resistance, and seam strength, so buyers can confirm the film will hold up under their specific dispensing and handling conditions. The reference data below is based on standard HDPE film and can be adjusted for heavier-duty or alternative resin specifications.

Physical Properties (Factory Lab Test Records) Test data based on 1.2 mil HDPE film. Actual performance can be adjusted per customer requirements (Data for reference only; certified test reports available upon request).
