>New Guardian produce a range of high quality and durable envelopes and mailing supplies. Their envelopes are available in a variety of sizes including C4, C5, DL and wage envelope size. They also have a variety of styles including gusset, board backed and internal mail.
New Guardian have added a new ‘easy open’ feature to a variety of their peel and seal envelopes in different sizes. This easy open feature provides a tear strip down the right hand side that allows you to quickly and neatly tear open the envelope without the risk of damaging the contents.
New Guardian use their Power Tac closure on their peel and seal envelopes which is an extremely strong adhesive providing a super sticky seal. From the moment you peel back the strip and close the envelope, your contents are secure and remain secure until the envelope is opened. This Power Tac technology also extends the shelf life of the envelopes compared to other seal types as they stay stickier for longer.
New Guardian firmly believe in protecting and preserving the environment around us. All of the New Guardian two tone envelopes are created using environmentally friendly manilla paper. A vast majority of New Guardian’s envelopes are also 100% recycled and recyclable. Using their envelopes will allow you and your business to take action and help protect the environment and improve your carbon footprint.
Armour gusset envelopes are made from heavyweight 130gsm manilla paper and are reinforced with a polyester thread woven in a grid pattern to the inside. This provides added strength and allows you to mail bulkier items such as lever arch files and box files without the worry of the envelope not standing up to the task at hand. These envelopes also feature the Power Tac seal which aids in the strengthening properties.
