Sapphire Heat Seal Bags – Pack of 1,000
Sapphire Heat Seal Bags make it straightforward to group, present and protect lightweight items. Their clear polythene construction keeps the contents visible, helping staff identify packed components, textiles or retail goods without opening each bag. The pack of 1,000 provides a useful supply for repeated packing tasks.
The open end allows you to load the bag and position the contents before closing it with an appropriate heat sealer. Leave sufficient spare film above the item to form a flat seal. A trial pack helps establish the right fit and sealing settings for your equipment and goods.
Choose the bag around the application. Lightweight film suits lighter items without sharp edges; it should not be used as a substitute for a heavy-duty sack, vacuum pouch or cooking bag. For direct food contact, confirm the bag specification and intended use, including the food type, storage time and temperature.
These bags can form part of a wider packing and preparation setup. Our Wrapmaster 4500 aluminium foil refills provide a separate wrapping option, while foil serving platters support food presentation. Choose each packaging format for its intended task.

Directions for Use
Check the bag and intended contents
Confirm the bag dimensions against the item before starting a packing run. Allow clearance around the contents and spare film at the opening for sealing. For food-contact applications, check suitability for the particular food and storage conditions before use.
Fill without stressing the film
Work on a clean, dry surface and open the bag carefully. Place the item inside without stretching the film or forcing corners against it. Keep the mouth of the bag free from the contents, folds and contamination so that it can lie flat in the sealer.
Set and test the heat seal
Use equipment suitable for polythene film and follow the sealer manufacturer's instructions. Set up the machine using a sample bag, inspect the resulting seal and adjust the settings as the equipment instructions allow. Do not assume one time or temperature will suit every sealer or bag grade.
Inspect and store the finished pack
Check that the closure is continuous and the film is free from holes or split edges. Support the contents during handling rather than lifting a heavy item by the bag opening. Store unused bags away from heat and direct sunlight, and confirm local collection arrangements before recycling clean polythene film.

FAQs
How many bags are supplied?
This listing is for a pack of 1,000 Sapphire Heat Seal Bags. Keep the pack in a clean, dry place and take out the quantity needed for the current job so that unused bags remain protected.
Do I need a heat sealer?
A suitable heat sealer is required to make a heat-sealed closure. The bag's open end is loaded first and then placed flat across the sealing area. Follow the equipment instructions and check a sample seal before processing a batch.
What bag size should I choose?
Measure the item at its widest point and allow room for easy loading, its depth and the closure. Confirm the dimensions of the supplied bag before ordering when fit is critical. A flat bag that matches only the item's face dimensions may be too tight once filled.
Can the bags be used for food?
Food-contact suitability depends on the exact bag specification and the application. Confirm the intended food, temperature and storage conditions before use. Heat sealing the opening does not make a bag suitable for cooking, boiling water or hot filling.
Are they suitable for vacuum packing or heavy parts?
Use packaging specifically designed for those tasks. These lightweight, open-ended bags are intended for general packing, and sharp edges or heavy contents can damage the film. A heat-sealed closure alone does not establish vacuum-packing performance.
Can used bags be recycled?
Check whether your waste contractor or local collection accepts this type of polythene film. Food residues and other contamination can affect acceptance. Keep suitable clean film separate where required by the collection service, and follow its sorting instructions.
