Bags / Polythene (Popular) / 700G - 1000G (178mu - 254mu)

* Many of our poly bags are suitable for food use, however there may be exceptions and if you specifically require this then it is best to get specific confirmation of this.

Clear Polythene Bags (700g–1000g) — Practical Overview

This collection groups heavier-gauge clear polythene bags commonly specified by weight-per-ream style grades (for example 700g and 750g) and by thickness in microns (for example 178µm and 191µm). In day-to-day use, these bags are chosen when a standard lightweight poly bag is not robust enough for handling, stacking, or protecting products with sharper edges. The bags in this range are typically used for industrial parts, printed materials, textiles, and general storage where clarity and toughness matter.

Because thickness is often the deciding factor, it helps to treat the “g” grade as a quick shorthand and the micron value as the technical measure. Microns (µm) describe film thickness directly; higher micron values generally mean a stiffer, stronger bag with improved puncture resistance and better performance during packing and transit. Clear film also supports quick visual identification of contents, which can reduce picking errors and speed up dispatch workflows.

Food-use note: some polythene bags can be suitable for food contact, but suitability depends on the specific product specification and intended use. If you require food-contact confirmation for a particular application, obtain explicit confirmation for the exact bag you plan to use.

Polythene Bags (Popular) 700g–1000g (178µm–254µm) — Helpful Guide

Within this category, you’ll mainly see clear bags made from thicker polythene film, with formats such as bottom-weld construction and options like paper-wrapped packing. Below is a practical guide to the types you’ll encounter and how to match them to your packing task.

1) Clear bottom-weld poly bags (general-purpose heavy gauge)

Bottom-weld bags are made from flat tubing sealed across the bottom edge. This construction is widely used because it is consistent, economical, and suitable for a broad range of products. In heavier gauges, bottom-weld bags are often selected for items that are bulky, have corners, or need extra protection against tearing during handling.

• 31x54 - 700g Clear Poly Bags (787x1372mm - 178mu) - Paper Wrapped
  Large-format clear bags in a heavy 178µm film. The paper-wrapped presentation can help keep packs tidy and easier to count/handle in a packing area.
• 31x54 - 700g Clear Poly Bags Misprinted (787x1372mm - 178mu)
  A functional option where the film and size are the key requirements. Often used where appearance is less critical than performance and cost control.

2) Clear bottom-weld poly bags (smaller format, paper wrapped)

Smaller heavy-gauge bags are commonly used for components, fasteners, spares, and boxed items where a tougher bag reduces split seams and punctures. Paper-wrapped packs can be convenient for storage and dispensing, especially where bags are issued in controlled quantities.

• 12x16" - 750g Clear B/Weld Poly Bags (305x406mm - 191mu) - Paper Wrapped
  A compact heavy-duty clear bag with a bottom weld and 191µm thickness, suited to parts, kits, and items that benefit from a stiffer film.

Case Study: Reducing Damage and Rework in a Busy Packing Area

A warehouse team packing mixed items (including boxed goods and products with corners) noticed frequent splits in lighter bags during end-of-line handling. The result was re-bagging, relabelling, and occasional scuffing of products. By moving to a heavier-gauge clear bag for the same pack format, they reduced bag failures during handling and improved consistency at dispatch.

Two operational changes made the difference: (1) selecting a thicker film to better resist punctures and stretching, and (2) standardising bag sizes so packers weren’t forcing items into undersized bags. Clear film also helped the team verify contents quickly, reducing picking errors and the need to open bags for checks.

How to Choose the Correct Bag (Size, Thickness, and Format)

Step 1: Confirm internal dimensions and loading method

Start with the product’s maximum length, width, and depth (or thickness). For flat items, internal width and length are usually enough. For bulky items, allow extra width for the product’s depth so the bag can close without overstressing the film. If you are inserting items quickly on a bench, a slightly larger opening can improve speed and reduce snagging.

Step 2: Choose thickness based on handling risk

Thickness is a practical proxy for durability. If your items have corners, edges, or are heavy for their size, a thicker film can reduce punctures and seam stress. If bags are stacked, dragged across benches, or handled repeatedly, heavier gauge can also improve reliability. Where appearance matters (for example, customer-facing presentation), consistent clear film and neat packing formats can help.

Step 3: Decide whether paper-wrapped packs suit your workflow

Paper-wrapped packs can be easier to store and dispense, particularly where you want to keep bags clean and flat until use. They can also help with counting and issuing stock. If your process involves high-speed dispensing from a box or rack, consider how the pack format integrates with your station layout.

Step 4: Consider closure and sealing requirements

This collection focuses on plain bags rather than specialist closures. If you need a tamper-evident seal, repeated opening/closing, or airtight performance, you may need a different bag type (for example, grip seal, adhesive strip, or heat-sealable formats). For plain bags, closure is often achieved with tape, ties, staples (where appropriate), or heat sealing if the film is suitable and your process allows it.

Performance and Material Notes (What “Clear Polythene” Means in Practice)

Clear polythene film is widely used because it is flexible, moisture resistant, and cost-effective. In heavier gauges, it becomes noticeably stiffer and more supportive, which can help bags hold their shape during packing. Clarity supports quick identification and can be useful for inventory control, kitting, and quality checks.

Polythene bags are commonly used as an outer protective layer to keep dust and moisture off products. They are also used as inner liners inside cartons to reduce scuffing and to keep sets of items together. For long-term storage, consider the storage environment (temperature, UV exposure, and compression) and whether you need additional protection such as desiccants or secondary packaging.

Common Uses for 700g–1000g Grade Bags

• Industrial parts and components: thicker film helps resist punctures from edges and corners.
• Printed materials and signage: clear film protects against moisture and handling marks while keeping contents visible.
• Textiles and soft goods: helps keep items clean and grouped without obscuring identification labels.
• Warehouse storage and kitting: supports consistent pack presentation and reduces rework from split bags.
• Oversized items: large-format bags can protect bulky products during internal movement and staging.

Handling Tips to Get the Best Results

• Avoid overfilling: forcing items into a tight bag increases stress at the weld and can lead to splits.
• Protect sharp edges: if items have sharp corners, consider adding a small card protector or wrapping the edge before bagging.
• Keep bags clean and flat: store packs away from dust and direct sunlight; keep them flat to reduce creasing and improve presentation.
• Standardise sizes: using a small set of standard bag sizes can speed up packing and reduce picking mistakes.
• Label placement: apply labels to a smooth area to reduce lifting; for large bags, place labels where they won’t be folded or creased.
