How Mailing bags are made?

Types of Mailing bags to suit applications

  • Economy lightweight postal mailers: Economy range for simple but effective protection - plain and coloured mailers plus the Maillite range with a pre-printed address window. The cheapest way to send literature to your customers and staff and much lighter than paper envelopes.
  • Blue opaque mail-order goods bags: A range of good value strong bags ideal for 'mail order' sales. Ideal for garments and a myriad of online or catalogue products. The bags are an attractive opaque metallic blue and are strong without being too thick and so expensive. A best seller line for eBay and PayPal customers selling their products on-line.
  • Heavy duty postal mailers: Thicker opaque mailers in a strong co-extruded material where you need to be sure that the mailer can withstand some rough handling in transit.
  • Large heavy duty courier sacks: Massively popular range of large and very large courier sacks with double seals. It is tough quality !
  • Metallic high impact silver mailers: 'Premium Quality' metallic silver mailing envelopes - ideal for high impact mailings.
  • Security mailers: Extra thick (360 gauge) white opaque mailers with a Tamper Evident Sealing Strip. The welds have a side skirt as well to give extra security to the package - for that top secret document!
  • Tamper evident mailers: Range of tamper evident bags available in clear as well as opaque for when bag contents need to be identified.
  • Superlight bubble mailers: The lightest protective envelope on the market today ! The stock range comes in white and silver sizes - waterproof too!
  • Featherpost 'jiffy style' padded mailers: The standard paper padded envelope with a self seal strip for closure. This range is bubble lined rather than pulp filled so whilst being padded to protect contents they are also very light.
  • Document enclosed envelopes: Adhesive backed pouches to give your despatch a professional look - adhere directly onto boxes or pallets with an extremely strong tack adhesive.
  • Paper feel plastic envelopes: A plastic envelopes with the feel of paper (but much stronger and waterproof of course).

Funny news

Homophobic Postal Workers Hijacking Gay Magazines

I live in Oakland, CA in the San Francisco Bay Area. A few weeks ago, I realized that I was missing issues from my OUT and The Advocate subscriptions since December. When I called the publishers' customer service line, they told me the issues had been returned by the Post Office as "Undeliverable". I haven't moved, nothing has changed about my mailbox. These subscriptions had been coming for several years to this same address without any problems. My other magazine subscriptions (WIRED, MacWorld, Premiere, Entertainment Weekly) have all been delivered without problems. There was no logical explanation for why the missing magazines would have been "undeliverable". It was a strange coincidence that both missing magazines were gay news magazines, both are delivered in opaque plastic mailers. I've reported the matter to the local PO Station which sorts mail for delivery for my route and had the publishers take the hold off my subscription. We'll see if the issues show up. I was wondering if anyone else has had delivery problems with their subscriptions to OUT, The Advocate or other gay news magazines. I'd also like to get help tracking which issues have been sent out and received. If other Advocate and OUT subscribers could post here the date they receive issues and which issues they received, it would help me keep tabs on delivery issues. Also if any staff from LPI reads this, I would be interested in bringing this to your attention and finding out how prevalent a problem this is. I've posted to another gay forum and so far one other person responded that they had a similar issue. The PO was at first reluctant to take action until the person had his lawyer contact the Post Office and the PO assigned a new mail carrier to the route. It's a Federal crime to tamper with the mail and mail delivery, I would hope that PO employees would also be subject to the same laws.
