Put items that you don't want to scratch on the surface! An example of consideration for protecting what is placed inside.
We would like to introduce a case where we produced "envelopes with protective film for lenses." The inner surface of the bag is almost entirely covered with a soft-touch rayon (non-woven fabric) film, which bends softly like waves, allowing it to gently adhere to the items inside and making it difficult to scratch them. Additionally, while the adhesive area is usually hidden on the inside of a standard envelope, we intentionally placed it on the outside to prioritize the smoothness of the contents. This design is intended for use with lenses for glasses and cameras, acrylic stands, LCD mobile phones, and mobile phone protective films. 【Case Overview】 ■ Features - The inner side of the bag is covered with a rayon (non-woven fabric) film to protect the lenses. - The adhesive area is on the outside, making it less prone to scratches. ■ Intended Uses - Lenses for glasses and cameras, acrylic stands, LCD mobile phones, mobile phone protective films, glass crafts, and delicate accessories. *For more details, please refer to the PDF document or feel free to contact us.

![[Processing Introduction] Types and Characteristics of Adhesives](https://image.mono.ipros.com/public/product/image/639/2001198481/IPROS11120862824307500543.jpeg?w=280&h=280)
We propose adhesive processing tailored to your needs and costs! Introduction to adhesive processing for envelopes.
We will introduce the types and features of adhesive processing for envelopes that we handle. Adhesive is applied to the flap and body, and by overlapping the adhesives of the flap and body, they are bonded together. Arabic adhesive is a type that can be bonded by moistening it with water, similar to a postage stamp. Double-sided tape has strong adhesion and can bond even to papers that are difficult for adhesives to stick to, while hot melt is a type of adhesive that applies a resin-based adhesive and attaches a thin release paper. We can propose adhesive processing tailored to your needs and budget, so please feel free to consult with us. 【Features】 ■ Adhesive - There is no need to protect with release paper, eliminating the hassle and waste of peeling off release paper. - Relatively inexpensive compared to other adhesive processing methods. ■ Arabic - Commonly used for C5-sized envelopes. - Using colored adhesive makes it easier to inspect for any missed application of the adhesive. *For more details, please refer to the PDF materials or feel free to contact us.
Cost reduction with just one face-up! It is possible to significantly reduce the number of sheets of paper used.
We would like to introduce the efficient layout of diamond envelopes that we are implementing. Unlike traditional Japanese or Western envelopes, diamond-shaped envelopes allow for efficient layout by being arranged diagonally. While arranging them vertically or horizontally results in only two envelopes fitting, arranging them diagonally enables the fitting of six envelopes, significantly reducing the number of sheets of paper used. Additionally, even with the same paper size, there can be a threefold difference in layout efficiency. 【Features】 ■ Efficient layout is possible by arranging diagonally ■ Reduces the amount of paper used ■ There can be a threefold difference in layout efficiency even with the same paper size *For more details, please refer to the PDF document or feel free to contact us.

Recommended when you want to differentiate from regular envelopes! It stands out enough to be noticeable at a glance.
We would like to introduce the processing of envelopes using vapor-deposited paper (metallic paper) that we handle. The biggest feature of vapor-deposited paper is its overwhelming brilliance that shines like metal.

Utilize the unique texture of the paper itself! A very stylish and high-quality envelope will be created.
We would like to introduce a case where we produced envelopes using paper with a laid pattern. Laid patterns can have the same direction as the paper grain or be in the opposite direction, so it is essential to check the actual direction of the laid pattern in the base paper.

No use of foaming ink or thermosensitive foaming paper! Can be recycled as regular paper.
We would like to introduce a case of producing "braille envelopes" at our company. In recent years, there has been an increase in inquiries about braille processing for envelopes, and we have conducted tests to see if braille can be read without being flattened due to the pressure during the bag-making process after braille printing. Issues such as braille being flattened or wrinkles appearing in the paper can occur depending on the type of paper used, the position of the braille, and the content, so we recommend proofreading and testing at the time of order. 【Case Overview】 ■ Specifications: Braille printing → Envelope bag-making ■ Features - Braille is created through pressing, and we do not use foaming inks or thermosensitive foaming paper. - Can be recycled as regular paper. *For more details, please refer to the PDF document or feel free to contact us.
