Envelope 27x36 cm Manufacturer,Supplier and Exporter in India

Envelope 27x36 cm (Product Code: SLE/CL/04) is a strong paper envelope of approximately 27x36cm with a water-resistant lining on the inside. The combination of a tough outer paper and a moisture-resistant inner layer helps protect paperwork, cards and bagged items from damp and handling while they are stored or sent between laboratory sections, clinics and referral sites. It is used across laboratory services from basic laboratories to reference centres and is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, a laboratory equipment supplier in India.

Specifications

Typical Use

Laboratories handle a steady flow of paper: request forms, result sheets, logbooks, quality-control records and filter-paper cards that must travel with samples or be archived. An envelope of this size takes standard A4 paperwork without folding, and its water-resistant lining gives extra protection against spills, condensation from cold boxes and humid transport conditions. Many sites place dried sample cards in a sealed plastic bag first and then slip the bag into the envelope with the accompanying forms, so everything for one batch stays together.

Write the destination, sender and batch details on the outside with a permanent marker before filling, and seal the envelope fully. Note that a lined paper envelope is not a leak-proof container for liquid specimens; those need dedicated sample transport packaging. Buying envelopes from the same lab consumables supplier in India that provides your tubes, bags and cards makes restocking simpler.
